    abstract = {Implementing machine learning in healthcare, especially for heart disease prediction , is crucial for saving lives through accurate diagnosis. Yet, the effectiveness of these models is constrained by a lack of extensive, annotated datasets, which are crucial for training robust models. Additionally, there is an under-use of existing knowledge graphs (KGs), which contain structured domain knowledge that could improve the performance of models. To address this challenge, our study introduces approaches that integrate KG embeddings with tabular data, with the goal of improving the performance of machine learning algorithms for heart disease prediction. We conduct a comparative analysis of various methodologies to merge tabular data with KGs, focusing on heart disease, and evaluate the performance of two embedding algorithms in augmenting datasets for more accurate machine learning applications. Our methodology, which involves testing embeddings from diverse KGs, has consistently shown improvements in model performance. Specifically , we increased the accuracy of the Feed-Forward Neural Network from 82% to 85% and the F2 score for the K-Nearest Neighbors model from 71% to 80%. This advancement offers a promising direction for leveraging semantic information from KGs for knowledge-enhanced machine learning in healthcare.},

    In line with the general trend in artificial intelligence research to create intelligent systems that combine learning and symbolic components, a new sub-area has emerged that focuses on combining Machine Learning components with techniques developed by the Semantic Web community—Semantic Web Machine Learning (SWeML). Due to its rapid growth and impact on several communities in thepast two decades, there is a need to better understand the space of these SWeML Systems, their characteristics, and trends. Yet, surveys that adopt principled and unbiased approaches are missing. To fill this gap, we performed a systematic study and analyzed nearly 500 papers published in the past decade in this area, where we focused on evaluating architectural and application-specific features. Our analysis identified a rapidly growing interest in SWeML Systems, with a high impact on several application domains and tasks. Catalysts for this rapid growth are the increased application of deep learning and knowledge graph technologies. By leveraging the in-depth understanding of this area acquired through this study, a further key contribution of this article is a classification system for SWeML Systems that we publish as ontology.

    abstract = {Log files are a vital source of information for keeping systems running and healthy. However, analyzing raw log data, i.e., textual records of system events, typically involves tedious searching for and inspecting clues, as well as tracing and correlating them across log sources. Existing log management solutions ease this process with efficient data collection, storage and normalization mechanisms, but identifying and linking entities across log sources and enriching them with background knowledge is largely an unresolved challenge. To facilitate a knowledge-based approach to log analysis, this paper introduces SLOGERT, a flexible framework and workflow for automated construction of knowledge graphs from arbitrary raw log messages. At its core, it automatically identifies rich RDF graph modelling patterns to represent types of events and extracted parameters that appear in a log stream. We present the workflow, the developed vocabularies for log integration, and our prototypical implementation. To demonstrate the viability of this approach, we conduct a performance analysis and illustrate its application on a large public log dataset in the security domain.},

Cyber-Physical (Energy) Systems (CP(E)S) are therefore increasingly complex and dynamic, with several stakeholders (end users, system operators) requiring explanations of the system status/behaviour. The development of solutions for explainable CP(E)S algorithms is however challenging because the deployment and testing in vivo of these solutions is restricted, if not impossible, in terms of the risks of modifying a critical infrastructure. In this paper, we present a semantics based solution to explainable CP(E)S and show how its development is supported by being able to test it in in vitro settings enabled by the BIFROST simulation engine.

    abstract = {Background. In Production Systems Engineering (PSE), the planning of production systems involves domain experts from various domains, such as mechanical, electrical and software engineering collaborating and modeling their specific views on the system. These models, describing entire plants, can reach a large size (up to several GBs) with complex relationships and dependencies. Due to the size, ambiguous semantics and diverging views, consistency of data and the awareness of changes are challenging to track. Aim. In this paper we explore visualizations mechanisms for a model inspection tool to support consistency checking and the awareness of changes in multi-disciplinary PSE environments, as well has more efficient handing of AutomationML (AML) files. Method. We explore various visualization capabilities that are suitable for hierarchical structures common in PSE and identified requirements for a model-inspection tool for PSE purposes based on workshops with our company partner. A proof-of concept software prototype is developed based on the elicited requirements. Results. We evaluate the effectiveness of our Information Visualisation (InfoVis) approach in comparison to a standard modeling tool in PSE, the AutomationML Editor. The evaluation showed promising results for handling large-scale engineering models based on AML for the selected scenarios, but also areas for future improvement, such as more advanced capabilities. Conclusion. Although InfoVis was found useful in the evaluation context, in-depth analysis with domain experts from industry regarding usability and features remain for future work.},

TD has also been introduced to systems engineering domain, to communicate design shortcomings in long-running, software-assisted systems. We analysed potential TD in the engineering data exchange for production system engineering. Similar to requirements engineering in software-intensive systems, data exchange in the design phase plays an integral part in Software Engineering (SE) for Production Systems Engineering: Specifications, and physical logic have to be derived from heterogeneous plant models or parameter tables designed by different stakeholders. However, traditional procedures and inadequate tool support lead to inefficient data extraction and integration. We identified debt arising from knowledge representation, data model and the exchange process. The refinement validation of identified TD was achieved through semi-structured interviews with representatives in two analysed companies. In an online survey with ten participants from an industrial consortium we evaluated whether the identified TD concepts also applied to other companies, which is true for the majority of TD. Furthermore, we discuss promising TD management strategies to repay and manage negative effects and the accumulation of additional debt, such as improved communication, test-driven model engineering and visualisation of engineering models.},

To scale up verification processes to larger groups of experts, Human Computation techniques were used focusing primarily on closed tasks, which constrain the number and variety of reported defects in favor of easy aggregation of derived judgements. To address this limitation of closed tasks, in this paper, we investigate EER verification (as instance of a broader family of model verification problems) with open tasks to extend the range of collected results. We also address the challenge of aggregating results of open tasks by proposing a followup HC task for defect validation. We evaluate our approach for HC-based EER Verification with open tasks in a set of experiments conducted with junior developers and show that (1) open tasks allow collecting a variety of insights that go beyond a manually built gold standard while still leading to good performance (F1=60\{\%\}) and (2) HC-based validation can be reliably used for validating the results of open tasks (F1=84\{\%\} compared to expert validation).},

    abstract = {Smart city infrastructures such as transportation and energy networks are evolving into so-called cyber physical social systems (CPSSs), which collect and leverage citizens' data in order to adapt services to citizens' needs. The privacy implications of such systems are, however, significant and need to be addressed. Current systems either try to escape the privacy challenge via anonymization or use very rigid, hard-coded workflows that have been agreed with a data protection authority. In the case of the latter, there is a severe impact on data quality and richness, whereas in the former, only these hard-coded flows are permitted resulting in diminished functionality and potential. We address these limitations via user modeling in terms of investigating how to model and semantically represent user consent, preferences, and data usage policies that will guide the processing of said data in the data lake. Data protection is a horizontal field and consequently very wide. Therefore, we focus on a concrete setting where we extend the domain-agnostic SPECIAL policy language for a smart mobility use case supplied by Vienna's largest utility provider. To that end, (1) we create an extension of SPECIAL in terms of a core CPSS vocabulary that lowers the semantic gap between the domain agnostic terms of SPECIAL and the vocabulary of the use case; (2) we propose a workflow that supports defining domain-specific vocabularies for complex CPSSs; and (3) show that these two contributions allow successfully achieving the goals of our setting.},

These complex systems can only be realized by tightly integrating components in the physical space (sensors, actuators) with advanced software algorithms in the cyber-space, thus creating so-called Cyber-Physical Systems(CPS). Semantic Web technologies (SWT) have seen a natural uptake in several areas based on CPS, given that CPS are data and knowledge intensive while providing advanced functionalities typical of semantics-based intelligent systems. Yet, so far, this uptake has primarily happened within the boundaries of application domains resulting in somewhat disconnected research communities. In this paper, we take a cross-domain perspective by synthesizing our experiences of using SWTs during the engineering and operation of CPS in smart manufacturing, smart buildings and smart grids. We discuss use cases that are amenable to the use of SWTs, benefits and challenges of using these technologies in the CPS lifecycle as well as emerging future trends. While non-exhaustive, our paper aims at opening up a dialog between these fields and at putting the foundation for a research area on semantics in CPS.},

    abstract = {The success of crowdsourcing based annotation of text corpora depends on ensuring that crowdworkers are sufficiently well-trained to perform the annotation task accurately. To that end, a frequent approach to train annotators is to provide instructions and a few example cases that demonstrate how the task should be performed (referred to as the CONTROL approach). These globally defined "task-level examples", however, (i) often only cover the common cases that are encountered during an annotation task; and (ii) require effort from crowdworkers during the annotation process to find the most relevant example for the currently annotated sample. To overcome these limitations, we propose to support workers in addition to task-level examples, also with "task-instance level" examples that are semantically similar to the currently annotated data sample (referred to as Dynamic Examples for Annotation, DEXA). Such dynamic examples can be retrieved from collections previously labeled by experts, which are usually available as gold standard dataset. We evaluate DEXA on a complex task of annotating participants, interventions, and outcomes (known as PIO) in sentences of medical studies. The dynamic examples are retrieved using BioSent2Vec, an unsupervised semantic sentence similarity method specific to the biomedical domain. Results show that (i) workers of the DEXA approach reach on average much higher agreements (Cohen's Kappa) to experts than workers of the the CONTROL approach (avg. of 0.68 to experts in DEXA vs. 0.40 in CONTROL); (ii) already three per majority voting aggregated annotations of the DEXA approach reach substantial agreements to experts of 0.78/0.75/0.69 for P/I/O (in CONTROL 0.73/0.58/0.46). Finally, (iii) we acquire explicit feedback from workers and show that in the majority of cases (avg. 72\{\%\}) workers find the dynamic examples useful.},

For an automatic PIO extraction, high-quality corpora are needed. Obtaining such a corpus from crowdworkers, however, has been shown to be ineffective since (i) workers usually lack domain-specific expertise to conduct the task with sufficient quality, and (ii) the standard approach of annotating entire abstracts of trial reports as one task-instance (i.e. HIT) leads to an uneven distribution in task effort. In this paper, we switch from entire abstract to sentence annotation, referred to as the SenBase approach. We build upon SenBase in SenSupport, where we compensate the lack of domain-specific expertise of crowdworkers by showing for each task-instance similar sentences that are already annotated by experts. Such tailored task-instance examples are retrieved via unsupervised semantic short-text similarity (SSTS) method – and we evaluate nine methods to find an effective solution for SenSupport. We compute the Cohen's Kappa agreement between crowd-annotations and gold standard annotations and show that (i) both sentence-based approaches outperform a Baseline approach where entire abstracts are annotated; (ii) supporting annotators with tailored task-instance examples is the best performing approach with Kappa agreements of 0.78/0.75/0.69 for P, I, and O respectively.},

    abstract = {Context: Software inspection represents an effective way to identify defects in early phase software artifacts, such as models. Unfortunately, large models and associated reference documents cannot be thoroughly inspected in one inspection session of typically up to two hours. Considerably longer sessions have shown a much lower defect detection efficiency due to cognitive fatigue. Goal: The goal of this paper is to propose and evaluate a Model Scoping approach to allow inspecting specific parts of interest in large models. Method: First, we designed the approach, which involves identifying Expected Model Elements (EMEs) in selected parts of the reference document and then using these EMEs to scope the model (i.e., remove unrelated parts). These EMEs can also be used to support inspectors during defect detection. We conducted a controlled experiment using industrial artifacts. Subjects were asked to conduct UML class diagram inspections based on selected parts of functional specificat ions. In the experimental treatment, Model Scoping was applied and inspectors were provided with the scoped model and the EMEs. The control group used the original model directly, without EMEs. We measured the inspectors' defect detection effectiveness and efficiency and collected qualitative data on the perceived complexity. Results: Applying Model Scoping prior to the inspection significantly increased the inspector defect detection effectiveness and efficiency, with large effect sizes. Qualitative data allowed observing a perception of reduced complexity during the inspection. Conclusion: Being able to effectively and efficiently inspect large models against selected parts of reference documents is a practical need, in particular in the context of incremental and agile process models. The experiment showed promising results for supporting such inspections using the proposed Model Scoping approach.},

Cybersecurity constitutes a particularly interesting domain for the development of a domain-specific public knowledge graph, particularly due to its highly dynamic landscape characterized by time-critical, dispersed, and heterogeneous information. To build and continually maintain a knowledge graph, we provide and describe an integrated set of resources, including vocabularies derived from well-established standards in the cybersecurity domain, an ETL workflow that updates the knowledge graph as new information becomes available, and a set of services that provide integrated access through multiple interfaces. The resulting semantic resource offers comprehensive and integrated up-to-date instance information to security researchers and professionals alike. Furthermore, it can be easily linked to locally available information, as we demonstrate by means of two use cases in the context of vulnerability assessment and intrusion detection.},

    abstract = {Managing privacy and understanding handling of personal data has turned into a fundamental right, at least within the European Union, with the General Data Protection Regulation (GDPR) being enforced since May 25th 2018. This has led to tools and services that promise compliance to GDPR in terms of consent management and keeping track of personal data being processed. The information recorded within such tools, as well as that for compliance itself, needs to be interoperable to provide sufficient transparency in its usage. Additionally, interoperability is also necessary towards addressing the right to data portability under GDPR as well as creation of user-configurable and manageable privacy policies. We argue that such interoperability can be enabled through agreement over vocabularies using linked data principles. The W3C Data Privacy Vocabulary and Controls Community Group (DPVCG) was set up to jointly develop such vocabularies towards interoperability in the context of data privacy. This paper presents the resulting Data Privacy Vocabulary (DPV), along with a discussion on its potential uses, and an invitation for feedback and participation.},

One of the main issues that inhibits data reuse and theemergence of vibrant data markets is the lack of standard mechanismsfor the execution of controlled transactions between data providers andconsumers, including efficient provisioning of data and associated ser-vices. Consequently, many potential data providers find it difficult toturn data into viable business models. At the same time, data consumersface challenges accessing heterogeneous data provided via various mech-anisms and have limited means to trace data provenance and ensuredata quality. Semantic Containers aim to tackle both issues by facili-tating controlled transactions through an integrated set of methods andcapabilities. Specifically, they package data, semantic descriptions, andprocessing capabilities into executable and shareable containers. In thispaper, we illustrate the concept by means of a pilot project in collabora-tion with the largest meteorological institute in Austria that illustrateshow Semantic Containers can be used to provide Seismic activity data},

    abstract = {Business process compliance checking enables organisations to assess whether their processes fulfil a given set of constraints, such as regulations, laws, or guidelines. Whilst many process analysts still rely on ad-hoc, often handcrafted per-case checks, a variety of constraint languages and approaches have been developed in recent years to provide automated compliance checking. A salient example is DECLARE , a well-established declarative process specification language based on temporal logics. DECLARE specifies the behaviour of processes through temporal rules that constrain the execution of tasks. So far, however, automated compliance checking approaches typically report compliance only at the aggregate level, using binary evaluations of constraints on execution traces. Consequently, their results lack gran-ular information on violations and their context, which hampers auditability of process data for analytic and forensic purposes. To address this challenge, we propose a novel approach that leverages semantic technologies for compliance checking. Our approach proceeds in two stages. First, we translate DECLARE templates into statements in SHACL, a graph-based constraint language. Then, we evaluate the resulting constraints on the graph-based, semantic representation of process execution logs. We demonstrate the feasibility of our approach by testing its implementation on real-world event logs. Finally, we discuss its implications and future research directions.},

Unfortunately, the heterogeneity of local engineering artifacts and data, coming from several engineering disciplines, makes it hard to integrate the discipline-specific views on the data for efficient synchronization. In this chapter, we introduce the approach of Engineering Data Logistics (EDaL) to support RTE requirements and enable the efficient integration and systematic exchange of engineering data in a PSE project. We propose the concept of EDaL that analyzes efficient Engineering Data Exchange (EDEx) flows from data providers to a consumer derived from data exchange use cases. Requirements for EDEx flows are presented, e.g. the definition and semantic mapping of engineering data elements for exchange. We discuss main requirements for and design elements of an EDaL information system for automating EDaL process capabilities. We evaluate the benefit and cost of the EDEx process and concepts in a feasibility case study with requirements and data from real-world use cases at a large PSE company in comparison to a traditional manual point-to-point engineering data exchange. Results from the feasibility study indicate that the EDEx process flows may be more effective than the traditional point-to-point engineering artifact exchange and a good foundation to EDaL as foundation for more agile engineering.},

They play an important role in a variety of domains ranging from industry to smart city applications. As such, these systems necessarily need to take into account, combine and make sense of heterogeneous data sources from legacy systems, from the physical layer and also the social groups that are part of/use the system. The collection, cleansing and integration of these data sources represents a major effort not only during the operation of the system, but also during its engineering and design. Indeed, while ongoing efforts are concerned primarily with the operation of such systems, limited focus has been put on supporting the engineering phase of CPSS. To address this shortcoming, within the CitySPIN project we aim to create a platform that supports stakeholders involved in the design of these systems especially in terms of support for data management. To that end, we develop methods and techniques based on Semantic Web and Linked Data technologies for the acquisition and integration of heterogeneous data from disparate structured, semi-structured and unstructured sources, including open data and social data. In this paper we present the overall system architecturewith a core focus on data acquisition and integration.We demon-strate our approach through a prototypical implementation of an adaptive planning use case for public transportation scheduling.},

    abstract = {Multi-disciplinary data exchange still poses many challenges: Heterogeneous data sources, diverging data views, and lack of communication lead to defects, late resolving of errors, and mismatches over the project lifecycle. Semantic approaches such as ontologies are a viable solution to derive common concepts between disciplines to limit negative effects in their collaboration. However, the application of these semantic approaches is still quite limited due to its inherent complexity. The purpose of this paper, is to discuss the concept of local glossaries as a step towards a Common Concept Glossary (CCG) method: A tool-supported method to enable and simplify the creation of common concepts derived from local glossaries that are built by discipline-specific workgroups. The local concepts can aid by making changes visible and enabling traceability and maintainability of common models between different disciplines.},

Unfortunately, the description languages used in a CPPS Engineering (CPPSE) organization to describe discipline-specific views are not necessarily well suited for high-quality data exchange between workgroups. In this paper, we identify technical debt and risks regarding CPPSE description languages for data exchange using the VDI 3695 guideline as best practice. We report on effects and likely causes of the quality risks identified in a case study at a large CPPSE company. Based on data from workshops and semi-structured interviews with 28 domain experts from 12 workgroups, we propose a preliminary model relating causes and effects as foundation for analyzing and managing risks in the CPPSE data exchange process.},

    abstract = {[Context] Models play an important role in Software and Systems Engineering processes. Reviews are well-established methods for model quality assurance that support early and efficient defect detection. However, traditional document-based review processes have limitations with respect to the number of experts, resources, and the document size that can be applied. [Objective] In this paper, we introduce a distributed and scalable review process for model quality assurance to (a) improve defect detection effectiveness and (b) to increase review artifact coverage. [Method] We introduce the novel concept of Expected Model Elements (EMEs) as a key concept for defect detection. EMEs can be used to drive the review process. We adapt a best-practice review process to distinguish (a) between the identification of EMEs in the reference document and (b) the use of EMEs to detect defects in the model. We design and evaluate the adapted review process with a crowdsourcing tool in a feasibility study. [Results] The study results show the feasibility of the adapted review process. Further, the study showed that inspectors using the adapted review process achieved results for defect detection effectiveness, which are comparable to the performance of inspectors using a traditional inspection process, and better defect detection efficiency. Moreover, from a practical perspective the adapted review process can be used to complement inspection efforts conducted using the traditional inspection process, enhancing the overall defect detection effectiveness. [Conclusions] Although the study shows promising results of the novel process, future investigations should consider larger and more diverse review artifacts and the effect of using limited and different scopes of artifact coverage for individual inspectors.},

    abstract = {[Context] Expertsourcing is a novel approach to model quality assurance: it relies on methods and tooling from crowdsourcing research to split the task of model quality assurance and parallelize its execution across several expert-users. Concretely, given a text-based system description and a corresponding model such as an EER diagram, experts are guided towards inspecting the model based on so-called expected model elements (EMEs). EMEs are entities, attributes and relations that appear in text and are reflected by the corresponding model. Therefore, EMEs play a crucial role in splitting up the model quality assurance task among experts. [Objective \{\&\} Method] In this paper, we investigate the effectiveness of identifying the EMEs themselves through expertsourcing. To that end, we perform a feasibility study in which we compare EMEs identified through expertsourcing with EMEs provided by a task owner who has a deep knowledge of the entire system specification text. [Conclusions] Results of the data analysis show that the effectiveness of the crowdsourcing- style EME acquisition is influenced by the complexity of these EMEs: entity EMEs can be harvested with high recall and precision, but the lexical and semantic variations of attribute EMEs hamper their automatic aggregation and reaching consensus (these EMEs are harvested with high precisions but limited recall). Based on these lessons learned we propose a new task design for expertsourcing EMEs.},

To address this challenge, researchers have recently introduced semantic web service composition methods. The growing interest in this topic of semantic web service composition has led to an increasing number of approaches, which has not been systematically surveyed so far. Researchers have reported several surveys in the related areas such as web service composition or semantic web service search. However, to the best of our knowledge, none of them provides a survey about these semantic web service compositions in particular. Hence, this review aims to address this issue by identifying existing efforts on semantic web service compositions. The survey focuses on two aspects (i) semantic web service description, as it is an essential aspect for semantic service composition, (ii) semantic web service composition, to identify methods and their implementations on the real world problem.},

The approach roots in belief revision theory and is capable of analyzing the user input, identifying the compliance with the existing structure and singling out new suggestions. When providing the update and upon submission the users obtain intuitive colorcoded feedback on their input w.r.t. to consistency and discrepancies with the existing knowledge. This feedback enables the educational aspect of the approach. The approach guarantees the consistency of the crowd-sourced knowledge when it is being integrated into the knowledge graph.},

We show how VeriCoM was applied in a software engineering use case focusing on verifying the correctness of an EER diagram against a system specification document. An evaluation of VeriCoM in a series of four workshops within one controlled experiment performed with a crowd of semi-experts lead to the identification of a set of defects with precision of 73\{\%\} and a recall from a Gold Standard defect set of 63\{\%\}.},

    abstract = {The recent developments in the engineering domain, often associated with the German term “Industrie 4.0”, require more flexible production systems. Such modern production systems are typically designed in Multi-Disciplinary Engineering Environments (MDEEs), where stakeholders from diverse engineering disciplines need to integrate data from heterogeneous data sources and manage changes within the integrated data sources, so that changes in one dataset are reflected in other relevant data sources. MDEEs, therefore, strongly rely on data integration across various stakeholders and engineering disciplines. Semantic Web Technologies support data integration using Ontology-Based Data Integration (OBDI) approaches, which, on their term are a prerequisite to support knowledge change management in MDEEs. Three variants of OBDI approaches have been proposed: single-ontology, multipleontology, and hybrid approaches. However, this classification is deemed too generic for understanding which approaches are most suitable in MDEEs. A first challenge, on the one hand, consists in understanding the suitability of OBDI approach variants for diverse MDEE scenarios and considering potential extensions thereof. On the other hand, since the topic of knowledge change management has been primarily investigated for single-ontology OBDI approaches, a second challenge therefore consists in providing knowledge change management techniques that are also applicable for more complex OBDI approaches (e.g., hybrid approaches). To address the first challenge, in this thesis, we evaluate the feasibility and suitability of OBDI approaches for diverse MDEE use cases. We propose a new OBDI variant called Global-as-View OBDI and distill criteria for classifying OBDI variants that allow for their informed selection for use in diverse MDEE scenarios. Our second line of work addresses the gap in supporting knowledge change management in complex OBDI variants. To that end, we define a set of knowledge change management requirements for complex OBDI in MDEE based on use cases from the engineering domain. Based on these requirements, we develop a generic, technology-agnostic framework of knowledge change management for hybrid and Global-as-View OBDI scenarios. To evaluate our approach, we instantiate the reference framework as a research prototype and conduct an initial feasibility study. The main outputs of the thesis are: (1) a systematic literature review on OBDI applications in MDEE, based on which we propose a new OBDI variant and guidelines for the selection of OBDI variants based on application context characteristics; (2) the evaluation of the OBDI selection guidelines to design concrete prototypes of OBDI applications for tackling two use cases in MDEEs; and (3) the definition of a generic knowledge change management framework for MDEEs and its feasibility evaluation.},

We investigate how and to what extent exploratory search can be supported on EKGs of architectural knowledge. We propose an approach for building exploratory search systems on EKGs and demonstrate its use within Siemens, which resulted in the STAR system used in practice by 200–300 software architects. We found that the EKG's ontology allows making previously implicit organisational knowledge explicit and this knowledge informs the design of suitable relatedness metrics to support exploration. Yet, the performance of these metrics heavily depends on the characteristics of the EKG's data. Therefore both statistical and user-based evaluations can be used to select the right metric before system implementation.},

Semantic Web technologies (SWTs) provide solutions for integrating and making sense of heterogeneous data sets and as such are a good solution candidate for solving data integration challenges in multi-disciplinary engineering (MDE) processes specific for the engineering of cyber-physical as well as traditional production systems. In this chapter, we investigate how SWTs can support multi-disciplinary engineering processes in CPPS.

    abstract = {Today's industrial production plants are complex mechatronic systems. In the course of the production plant lifecycle, engineers from a variety of disciplines (e.g., mechanics, electronics, automation) need to collaborate in multi-disciplinary settings that are characterized by heterogeneity in terminology, methods, and tools. This collaboration yields a variety of engineering artifacts that need to be linked and integrated, which on the technical level is reflected in the need to integrate heterogeneous data. Semantic Web technologies, in particular ontology-based data integration (OBDI), are promising to tackle this challenge that has attracted strong interest from the engineering research community. This interest has resulted in a growing body of literature that is dispersed across the Semantic Web and Automation System Engineering research communities and has not been systematically reviewed so far. We address this gap with a survey reflecting on OBDI applications in the context of Multi-Disciplinary Engineering Environment (MDEE). To this end, we analyze and compare 23 OBDI applications from both the Semantic Web and the Automation System Engineering research communities. Based on this analysis, we (i) categorize OBDI variants used in MDEE, (ii) identify key problem context characteristics, (iii) compare strengths and limitations of OBDI variants as a function of problem context, and (iv) provide recommendation guidelines for the selection of OBDI variants and technologies for OBDI in MDEE.},

Reviews are well-established methods for model quality assurance that support early and efficient defect detection. However, traditional document-based review processes have limitations with respect to the number of experts, resources, and the document size that can be applied. [Objective] In this paper, we introduce a distributed and scalable review process for model quality assurance to (a) improve defect detection effectiveness and (b) to increase review artifact coverage. [Method] We introduce the novel concept of Expected Model Elements (EMEs) as a key concept for defect detection. EMEs can be used to drive the review process. We adapt a best-practice review process to distinguish (a) between the identification of EMEs in the reference document and (b) the use of EMEs to detect defects in the model. We design and evaluate the adapted review process with a crowdsourcing tool in a feasibility study. [Results] The study results show the feasibility of the adapted review process. Further, the study showed that inspectors using the adapted review process achieved results for defect detection effectiveness, which are comparable to the performance of inspectors using a traditional inspection process, and better defect detection efficiency [Conclusions] Although the study shows promising results of the novel inspection process, future investigations should consider larger and more diverse review artifacts and the effect of the limited scope of artifact coverage for an individual inspector.},

However, considerable amount of data in open data portals remain inaccessible as linked data. This is due to the nature of data portals having large number of small-size dataset which makes writing mapping description becomes tedious and error-prone. Moreover, these data sources requires additional preprocessing before To solve this challenge, We introduce extensions to RML to support required tasks and developed RMLx, a visual web-interface to create RML mappings. Using this interface, the process of creating mapping description can become faster and less error-prone. Furthermore, the process of linked data generation can be wrapped as to enable integration with other data in a linked data exploration environment. We explore on four different use cases to identify the requirements followed by describing how these are solved.},

However, insufficient method and tool support hinder efficient defect detection in large software models. Recent Human Computation and Crowdsourcing processes may help to overcome this limitation by splitting complex inspection artifacts into smaller parts including a better control over defect detection tasks and increasing the scalability of inspection tasks. Therefore, we introduce a Crowdsourcing-Based Inspection (CSI) process with tool support with focus on inspection teams and the quality of defect detection. We evaluate the CSI process in a feasibility study involving 63 inspectors using the CSI process and 12 inspectors using a traditional best-practice inspection process. The CSI process was found useful by the participants. Although the preliminary results of the study were promising, the CSI process should be further investigated with typical large software engineering models.},

However, the actual use of the available open data sets is still rather limited in many sectors. Consequently, the potentials of available open data sets are not fully realized, which may discourage open data publishers. To encourage a broader adoption of open data and to contribute towards making democratic processes more transparent, critical data journalism is essential. In this demo paper, we propose an approach called Open Data Mashups for Data Journalism (ODMOJO) that aims to bridge open data publishers and their consumers, i.e., journalists and society at large, with Linked Data technologies. Specifically, our approach will facilitate the access, reuse, and integration of open data for General Data Journalism. We plan to evaluate our approach with potential journalism partners as well as open data publishers in Austria, to foster further adoption and utilization of open data through data journalism and Linked Data technologies.},

Shifting testing and tuning of industrial plants and their automation systems from the real world to simulated environments is a part of a virtualization, which is one of the key movements in emerging areas of Industry 4.0 and factories of the future. Although simulations bring a large variety of benefits, they suffer from a time-consuming and error-prone design phase, which limits their use in industrial practice. This paper proposes a new design method called AML2SIM, which transforms the real plant description represented in AutomationML (AML) and generates a dynamic simulation model (SIM). The proposed method signifcantly improves the engineering and re-design of simulation models in terms of saving time and effort of experts as the models can be easily re-generated based on a given AutomationML plant model. Simulations are assembled from simulation blocks that are shared among various projects in simulation libraries, hence the method contributes to reuse of simulation artifacts.},

    abstract = {This chapter is focused on the technical aspects of semantic data inte-gration that provides solutions for bridging semantic gaps between common project-level concepts and the local tool concepts as identified in the Engineering Knowledge Base (EKB). Based on the elicitation of use case requirements from automation systems engineering, the chapter identifies required capabilities an EKB software architecture has to consider. The chapter describes four EKB software architecture variants and their components, and discusses identified drawbacks and advantages regarding the utilization of ontologies. A benchmark is defined to evaluate the efficiency of the EKB software architecture variants in the context of selected quality attributes, like performance and scalability. Main results suggest that architectures relying on a relational database still outperform traditional ontology storages while NoSQL databases outperforms for query execution. In large-scale systems engineering projects, like power plants, steel mills, or car manufactures, the seamless cooperation and data exchange of expert knowledge from various engineering domains and organizations is a crucial success factor (Biffl et al. 2009a). This environment consists of a wide range of engineering systems and tools that differ in the underlying technical platforms and the used data models. Each domain or organization usually prefers using their own well-known models, from now on referred as local tool models. In order to successfully develop projects, it is essential to integrate important knowledge of different domain experts. However, these experts usually prefer using their well-known local tool models. In addition, they want to access data from other tools within their local data repre-sentation approach (Moser and Biffl 2012). The standardization of data interchange is one of the most promising approaches (Wiesner et al. 2011) to enable efficient data integration that allows experts to continue using their familiar data models and formats. This approach is based on agreeing on a minimal common model for data exchange that represents the common concepts shared among different disciplines on project level. Chapter 2 presented main use cases with typical process steps during the engineering phase within the life cycle of production systems. Selected scenarios focused on the capability to interact appropriately within a multidisciplinary engineering network while pointing out the need for a common vocabulary over all engineering disciplines involved in an engineering organization. The described challenges in the context of engineering data integration referred to a consistent production system plant model in order to support quality-assured parallel engi-neering, and the ability to access and analyze integrated data, e.g., for project progress and project quality reports. Versioning of exchanged information helps to improve change management and team collaboration over the course of the engi-neering project. As part of an efficient data management it is essential for process observations, project monitoring, and control across engineering disciplines (Moser et al. 2011b). As a common baseline it can be concluded that it is necessary to clearly dis-tinguish between local concepts of engineering tools and common concepts (Moser and Biffl 2010) (i.e., data sets representing heterogeneous but semantically corre-sponding local data elements) at project level. Consequently, interoperability between heterogeneous engineering environments is only supported if the semantic gap between local tool concepts and common project-level concepts can be prop-erly bridged. The Engineering Knowledge Base (EKB) (Moser and Biffl 2010) (see Chap. 4) provides the means for semantic integration of the heterogeneous models of each discipline using ontologies, and thus facilitates seamless communication, interaction, and data exchange. Semantic technologies are capable of linking cor-responding local concepts of engineering tools with each other via common project-level concepts representing the data integration needs of engineering dis-ciplines at their interfaces. 182 R.

    abstract = {©2016 IEEE. Typical large-scale systems engineering projects depend on seamless cooperation and data exchange of experts from various engineering domains and organizations that work in a heterogeneous engineering environment. Available software tools support individual engineering disciplines quite well, but they only represent a discipline-specific view on the engineering plant. Consequently, a so-called integrated plant model captures and combines all different views into one representation in order to provide an overarching, discipline-independent view on the engineering plant. However, in order to support effective engineering processes, like change management, stakeholders need to be able to (a) define the scope of their changes they want to merge into the integrated plant model rather than the latest status of their view with various fragile adaptations, and (b) extract only engineering information from integrated plant model which is in the scope of the stakeholders's discipline and interest. In this paper, we describe requirements identified in industrial use cases regarding filtering capabilities on (integrated) engineering plant models and model-driven engineering techniques for model-slicing applied on AutomationML models. The approach contributes to quality assurance and fault-prevention in engineering data since it helps to focus on parts of the engineering plant model relevant in certain engineering processes.},

    abstract = {©2016 IEEE. [Context] In Multi-Disciplinary Engineering (MDE) environments, the engineering of industrial production systems requires the collaboration of engineers coming from different disciplines. Engineers typically apply discipline specific tools and data models with limited collaboration capabilities. These loosely coupled tools and heterogeneous data models hinder efficient change management and defect detection, which makes MDE projects unnecessarily risky and error prone. [Objective] This paper presents an adapted review approach, AML-Review, for multi-disciplinary engineering (MDE) projects based on best practices for reviews in software engineering. [Method] Software reviews have been successfully used for early defect detection in Software Engineering. However, adaptations are needed for defect detection in MDE environments. We focus on production systems models according to the emerging AutomationML standard. [Results] We evaluated the feasibility of the AML-Review process with requirements and an AutomationML model from a real-world application scenario. The AML-Review process provides the benefits of systematic and traceable review results for MDE projects based on AutomationML. [Conclusion] The prototype results imply that systematic and structured review processes help to improve traceability of requirements and defects and increase defect detection performance.},

Recently, Semantic Web Technologies (SWT) have been introduced and adopted to address the problem of enterprise data integration (e.g., to solve the problem of terms and concepts heterogeneity within large organizations). One of the challenges of adopting SWT for enterprise data integration is to provide the means to define and validate structural constraints over Resource Description Framework (RDF) graphs. This is difficult since RDF graph axioms behave like implications instead of structural constraints. SWT researchers and practitioners have proposed several solutions to address this challenge (e.g., SPIN and Shape Expression). However, to the best of our knowledge, none of them provide an integrated solution within open source ontology editors (e.g., Protégé). We identified this absence of the integrated solution and developed SHACL4P, a Protégé plugin for defining and validating Shapes Constraint Language (SHACL), the upcoming W3C standard for constraint validation within Protégé ontology editor.},

The engineering phase of Cyber-Physical Production Systems (CPPS) is a multi-disciplinary process in which representatives of diverse engineering disciplines collaborate to deliver a complex CPPS. To ensure optimal project management as well as to avoid risks of inconsistencies between engineering models created by engineers from different disciplines, support is needed for integrating and subsequently analyzing diverse engineering data. AutomationML is an emerging data exchange format for engineering data which makes the first step towards the easier exchange of engineering data. Yet, there is a lack of tool support for integrating, making sense of and analyzing AML files. In this paper, we explore the use of Semantic Web and Linked Data technologies to provide extended functionality on top of AML that allows advanced data analytics on engineering data such as intuitive browsing of interlinked engineering models and queries for project-wide verification and validation activities. As a result of these investigations, we present the AutomationML Analyzer prototypical implementation to showcase some of the functionalities made possible by Semantic Web and Linked Data technologies in this context.},

A survey of tourism practitioners performed in this study showed that although such cross-domain analytics are important, they are primarily performed by relying on manual data collection and aggregation, which is both time-consuming and error-prone. This paper investigates the suitability of Linked Data technologies to support data aggregation tasks needed for establishing such complex analytics systems. To that end, a prototypical implementation is developed that relies on Linked Data as a technological platform for integrating data from three major tourism data sources: TourMIS, World Bank and Eurostat. Enabled by this integrated data, the ETIHQ Dashboard for data analytics was implemented, the first visual data analytics system that supports cross-domain analytics over tourism, economic and sustainability indicators. An exploratory evaluation performed with practitioners shows that this Linked Data enabled system could potentially bring important improvements in terms of execution times and answer quality when compared to current manual approaches typically used by tourism practitioners in daily practice. ©2016, Springer-Verlag Berlin Heidelberg.},

The process of designing Cyber Physical Production Systems (CPPS), e.g., modern power plants or steel mills, typically takes place in a multi-disciplinary engineering environment, in which experts from various engineering domains and organizations work together towards creating complex engineering artifacts. The process of designing such complex engineering artifacts requires iterations and redesign phases, which lead to continuous changes of the data and knowledge. To manage changes in such environment, we have previously proposed a generic reference process for conducting Knowledge Change Management and Analysis (KCMA). This paper implements this process for the case study of a modern Hydro Power Plant by adapting the proposed generic reference process into a scientific prototype developed using Semantic Web Technologies. Finally, we conduct an evaluation to evaluate the feasibility of the proposed reference process and the developed prototype. Thus, the contribution of this paper is twofolds: (1) A tool-supported prototype for KCMA of a hydro power plant, and (2) A feasibility evaluation of this prototype that reports feedback and lessons learned for achieving KCMA in real-world case studies.},

Current approaches to ontology change mainly focus on a single ontology and therefore do not properly address the constraints specific to OBII systems. To address the challenge of ontology change in OBII contexts, we plan to adapt successful techniques proposed both by Semantic Web and Model-Driven Engineering communities.

Standards such as the W3C RDF data cube vocabulary and the content-oriented guidelines of SDMX provide a foundation to tackle these challenges. In this paper, we introduce a framework that semi-automatically performs semantic data integration on statistical raw data sources at query time. We follow existing standards to transform non-semantic data structures to RDF format. Furthermore, we describe each data set with semantic metadata to deal with inconsistent use of terminologies. This metadata provides the foundation for cross-dataset querying through a mediator that rewrites queries appropriately for each source and returns consolidated results.},

Multi-Disciplinary Engineering (MDEng) environments involve a wide range of models, processes and tools that were not designed to cooperate together.

However, knowledge changes management and analysis (KCMA) process within the environ-ment are not covered within the OBII approach. While the tradi-tional ontology change management approach has been investi-gated to the general problem, it remains unclear how to use the available solutions within MDEng context.

We have identified the main KCMA requirements within MDEng projects and studied the related work of Ontology Change Management to propose a suitable solution, as well as suggesting further works.},

In this context, the use of increasingly abundant statistical data available on the web creates new opportunities for interesting applications and facilitates more informed decision-making. For the majority of end users, however, viable means to explore statistical data sets available on the web are still scarce. Gathering and relating statistical data from multiple sources is hence typically a tedious manual process that requires significant technical expertise. Data that is being published with associated semantics, using standards such as the W3C RDF Data Cube Vocabulary, lays the foundation to overcome such limitations. In this paper, we develop a semantic metadata repository that describes each statistical data set and develop mechanisms for the interconnection of data sets based on their metadata. Finally, we support users in exploring data sets through interactive mashups that facilitate data integration, comparisons, and visualization.},

The recent industrial adoption of Semantic Web techniques, which rely on ontologies, has led to the increased importance of the ontology evolution research. Typical approaches to ontology evolution are designed as multiple-stage processes combining techniques from a variety of fields (e.g., natural language processing and reasoning). However, the few existing surveys on this topic lack an in-depth analysis of the various stages of the ontology evolution process. This survey extends the literature by adopting a process-centric view of ontology evolution. Accordingly, we first provide an overall process model synthesized from an overview of the existing models in the literature. Then we survey the major approaches to each of the steps in this process and conclude on future challenges for techniques aiming to solve that particular stage.},

Unfortunately, relevant knowledge collected in the SLR process is not publicly available, which considerably slows down building BoKs incrementally. Objective. We present and evaluate the Systematic Knowledge Engineering (SKE) process to support efficiently building BoKs from published research. Method. SKE is based on the SLR process and on Knowledge Engineering practices to build a Knowledge Base (KB) by reusing intermediate data extraction results from SLRs. We evaluated the feasibility of applying SKE by building a Software Inspection BoK KB from published experiments and a Software Product Line BoK KB from published experience reports. We compared the effort, benefits, and risks of building BoK KBs regarding the SKE and the traditional SLR processes. Results. The application of SKE for incrementally collecting and organizing knowledge in the context of a BoK was feasible for different domains and different types of evidence. While the efforts for conducting the SKE and traditional SLR processes are comparable, SKE provides significant benefits for building BoKs. Conclusions. SKE enables researchers in a scientific community to reuse and incrementally build knowledge in a BoK. SKE is ready to be evaluated in other software engineering domains.},

Yet, they are mainly being used as external means to ontology engineering, without being closely integrated into the work of ontology engineers. In this paper we investigate how to closely integrate crowdsourcing into ontology engineering practices. Firstly, we show that a set of basic crowdsourcing tasks are used recurrently to solve a range of ontology engineering problems. Secondly, we present the uComp Protégé plugin that facilitates the integration of such typical crowdsourcing tasks into ontology engineering work from within the Protégé ontology editing environment. An evaluation of the plugin in a typical ontology engineering scenario where ontologies are built from automatically learned semantic structures, shows that its use reduces the working times for the ontology engineers 11 times, lowers the overall task costs with 40\{\%\} to 83\{\%\} depending on the crowdsourcing settings used and leads to data quality comparable with that of tasks performed by ontology engineers.},

However, the SKE process does not explain how to effectively capture and represent the EMSE knowledge to enable efficient data analysis. In this paper, we introduce the EMSE Research Knowledge Base Building (RKB) process, which guides knowledge engineers in developing and using a knowledge base (KB) for the SKE process based on contributions from heterogeneous data sources. We evaluate the RKB process in the context of three research topics from the EMSE domain: software inspection experiments, theory construct identification, and threats to validity. Major results are that the RKB process is effective in guiding the knowledge engineer to build a KB that allows answering the EMSE-specific queries. The RKB process shows promising results in the EMSE research context and should be investigated in other research contexts as well.},

In this paper we explore how Semantic Web technologies can address this challenge and present the Ontology-based Cross-Disciplinary Defect Detection (OCDD) approach that supports automated cross-disciplinary defect detection in ME environments, while allowing engineers to keep their well-known tools, data models, and their customary engineering workflows. We evaluate the approach in a case study at an industry partner, a large-scale industrial automation software provider, and report on our experiences and lessons learned. Major result was that the OCDD approach was found useful in the evaluation context and more efficient than manual defect detection, if cross-disciplinary defects had to be handled.},

    abstract = {©Copyright 2014 ACM. An engineering project consortium represents the collaboration of different groups of partners to achieve a common goal, e.g., developing innovative products. This collaboration may be challenging because of different terminologies and different tools and data models used by the project partners. In this work, we present the concept of a Project Consortia Knowledge Base (PC-KB), an integration framework based on semantic knowledge that facilitates project-level communication as well as access to and querying of project data across tool and partner boundaries. The PC-KB allows establishing common data models on different abstraction layers within the consortium organization. Using these common models, the PC-KB integrates partner data to provide (a) a common terminology for facilitating communication among project partners and (b) a common consistent view for efficient data integration. The PC-KB has been successfully applied in the automation systems domain to improve collaboration and data exchange in heterogeneous engineering environments.},

    abstract = {[Context] Empirical software engineering (EMSE) researchers conduct systematic literature reviews (SLRs) to build bodies of knowledge (BoKs). Unfortunately, valuable knowledge collected in the SLR process is publicly available only to a limited extent, which considerably slows down building BoKs incrementally. [Objective] In this paper, we introduce the Systematic Knowledge Engineering (SKE) process to support building up BoKs from empirical studies efficiently. [Method] SKE is based on the SLR process and on Knowledge Engineering (KE) practices to provide a Knowledge Base (KB) with semantic technologies that enable reusing intermediate data extraction results and querying of empirical evidence. We evaluated SKE by building a software inspection EMSE BoK KB from knowledge acquired by controlled experiments. We elicited relevant queries from EMSE researchers and systematically integrated information from 30 representative research papers into the KB. [Results] The resulting KB was effective in answering the queries, enabling knowledge reuse for analyses beyond the results from the SLR process. [Conclusion] SKE showed promising results in the software inspection context and should be evaluated in other contexts for building EMSE BoKs faster.},

Climate Quiz uses this paradigm for acquiring environmental domain knowledge from non-experts. The game's usage statistics and the quality of the produced data show that Climate Quiz has managed to attract a large number of players but noisy input data and task complexity led to low player engagement and suboptimal task throughput and data quality. To address these limitations, the authors propose embedding the game into a hybrid-genre workflow, which supplements the game with a set of tasks outsourced to micro-workers, thus leveraging the complementary nature of games with a purpose and mechanised labour platforms. Experimental evaluations suggest that such workflows are feasible and have positive effects on the game's enjoyment level and the quality of its output.},

To improve this drawback, user-friendly Ontology Query Tools (OQTs) have been introduced. However, there is, to our knowledge, no comprehensive framework for researchers and practitioners to compare the capabilities of the wide range of available OQTs. In this paper we introduce, based on a systematic literature review, a framework that allows researchers and practitioners to classify and compare OQTs regarding their capabilities and their support for relevant user types and scenarios. We evaluate the framework based on a real-world use case. Major result of the evaluation was that the framework was found useful and usable by users from the target audience to identify the most suitable OQTs for their context.},

The project managers have the responsibility to manage the OSS development in a way that the OSS product can be delivered to the customers in time and with good quality. This responsibility is challenging, because the heterogeneity of the data collected and analyzed from different stakeholders leads to the complexity of efforts of the project managers to measure and manage OSS projects. In this paper, we propose a measurement framework (OSMF) to enable the project managers to collect and analyze process data from OSS projects efficiently. Initial results show that OSMF can help project managers to manage OSS business processes more efficient, hence improve the decision on OSS project quality. ©2013 Springer-Verlag.},

    abstract = {The increased availability and robustness of sensors, the wide-spread use of the internet as a communication environment and the intensified adoption of semantic technologies foster the vision of embedding intelligence in physical objects. The race of realizing this vision is pervasive to a variety of research fields, most notably ambient intelligence and semantic web, and leads to the proliferation of several overlapping definitions and terminologies: smart products, semantic devices, semantic gadgets - to which we collectively refer to as smart objects. What exactly are smart objects? And what are the research challenges in realizing them? We hereby explore the answers to these questions.},
