Keynote 1 : A calculus for requirements engineering founded on argumentation theory.
Prof. John Mylopoulos, University of Toronto (Canada)
Session chair: Manuel Kolp

Room 2215

Abstract :

The requirements problem consists of transforming stakeholder requirements - however informal, ambiguous, conflicting, unattainable, imprecise and incomplete – into a consistent, complete and realizable specification through a systematic process. We propose a refinement calculus for requirements engineering (CaRE) for solving this problem, which is inspired by the typically dialectical nature of requirements activities. The calculus casts the requirement problem as an iterative argument between stakeholders and requirements engineers, where posited requirements are attacked for being ambiguous, incomplete, etc. and refined into new requirements that address the defect pointed out by the attack. Refinements are carried out by operators provided by CaRE that refine (e.g., strengthen, weaken, decompose) existing requirements to eliminate the defect under attack, to build a refinement graph. The semantics of refinement graphs is based on the notion of acceptable argument in Dung’s argumentation theory.

This is joint work with Yehia ElRakaiby, Alessio Ferrari and Alex Borgida.

Paper 5 (Short Paper): A Discussion of the Impact of Judgmental Heuristics on Elicitation during Requirements Engineering.
Corentin Burnay, Ivan Jureta and Stéphane Faulkner

Abstract :

A stakeholder decides which information to share during requirements elicitation. These decisions are made under uncertainty: stakeholders may not have precise, concrete, and complete information about their own expectations from, or about the environment of the system-to-be, they may misunderstand information which a requirements engineer gives them, and they may not have perfect knowledge about the various opportunities that the current technology may offer. Stakeholders’ decisionmaking is therefore likely to involve the use of heuristics. Understanding if stakeholders do indeed use heuristics during requirements elicitation, and if so, then which ones, should help understand requirements elicitation better, and design methods which can stimulate positive heuristics (those which help elicit relevant requirements) and mitigate negative ones. This paper defines what an elicitation heuristic may be, and proposes a set of research questions under the form of a matrix for the theoretical and empirical study of elicitation heuristics.

Paper 88 (Short Paper): Towards Detecting and Mitigating Conflicts for Privacy and Security Requirements.
Duaa Alkubaisy, Karl Cox and Haralambos Mouratidis

Abstract :

Requirement engineering live in a world were contradiction is the norm. Hence, development of software engineering is usually an adjustable and upgrading cyclical process. We found in the literature that some requirements conflict with other requirements. We will focus in this study on identification and resolution of conflicts between security and privacy requirements. Although, most the recent studies focus on identifying conflicts without proposing a solution to resolve it. This paper presents an approach to identifying and resolving conflicting privacy and security requirements as patterns. By using patterns to describe the problem, we can propose a solution for each conflict.

Paper 90 (Full Paper): Utilizing User Values to Generate System Requirements for a Geographically-dispersed Workforce.
Eric-Oluf Svee

Abstract :

A geographically-dispersed user base presents challenges for requirements engineering in enterprise systems, with problems including limited access to end users, a lack of trust between users and developers, and poor informal communication. Not only must these standard organizational and personnel difficulties be taken into consideration, but geographic dispersal also complicates the steps of the requirements engineering process. This paper investigates whether a method can be created to develop requirements for just such geographically-distributed outposts within the same organization. A psychological instrument that measures basic values was coupled with individual interviews to collect the value profiles for frontline security guards throughout Sweden. The results were used to generate requirements for field equipment, with goal- and feature models generated as a final result.

Paper 54 (Full Paper): The Effects of Consumer Interests in Top Box Office Movies in Thailand: evidence from the pre-during-post-peak periods.
Mathupayas Thongmak

Abstract :

This paper examined the information searches by consumers for movies from one-year Google Trends data and their relationship with the top box-office movies’ performance. Top five box-office movie data over a 53-week period were collected from boxofficemojo.com and Google Trends. Both Web search and YouTube search in the Arts & Entertainment category and the Online Communities category were explored. Two hundred sixty-five movies, listed in Thailand box office in 2017, were gathered for the analysis phase. Interest over time scores, showing relative search volume from Google Trends, represented the level of consumers’ interests in the movies over time. This study tried to investigate the impacts of consumer interests before, during, and after the peak period on the rank of the movie. Results partially supported the correlations between consumer interests in the pre-peak period and the movie rank, fully supported the correlations between consumer interests in the during-peak period and the movie rank, and supported the correlations between consumer interests in the post-peak period and the movie rank. Findings also indicated higher consumer interests in the during-peak period than the pre-peak period and higher consumer interests in the during-peak period than the post-peak period. In addition, there were an association between two movie ranks in consecutive week and a positive correlation between the latest movie rank and the time to be on the top box office chart.

Paper 66 (Short Paper): Fault Detection of Elevator Systems Using Deep Autoencoder Feature Extraction.
Krishna Mohan Mishra, Tomi R. Krogerus and Kalevi J. Huhtala

Abstract :

In this research, we propose a generic deep autoencoder model for automated feature extraction from the raw sensor data. Extracted deep features are classified with random forest algorithm for fault detection. Sensor data are labelled as healthy and faulty based on the maintenance actions recorded. The remaining healthy data is used for validation of the model to prove its efficacy in terms of avoiding false positives. We have achieved 100% accuracy in fault detection along with avoiding false positives based on new extracted deep features, which outperform the results using existing features. Existing features are also classified with random forest to compare results. Deep autoencoder random forest provides better results due to the new deep features extracted from the dataset when compared to existing features. Our model provides good classification and is robust against overfitting characteristics. This research will help various predictive maintenance systems to detect false alarms, which will reduce unnecessary visits of service technicians to installation sites.

Tutorial 1: Evaluating Artifacts using Experiments as part of the Design Science Framework.
Author: Gondy Leroy.
Session chair: Yves Wautelet
Room 3

Abstract :

Design science is of increasing importance in information systems (IS) with top journals and funding agencies recognizing it as an important component of IS research. One critical element of good design science is a solid evaluation of the artifacts, i.e., of individual algorithms and completed information systems. This tutorial focuses on the design and execution of experiments to evaluate such artifacts in an efficient manner. The artifact’s life cycle is taken into account to ensure the evaluation is appropriate, effective and efficient through optimal use of resources. Evaluations can range from automated evaluations of algorithms using gold standards to user studies of an entire information system with representative users in situ. The tutorial will focus on the controlled experiment for artifacts, appropriate statistical analysis, and tips on common errors that can be avoided.

Paper 11 (Short Paper): Design for Efficient Production, a Model-Based Approach.
Thomas Polacsek, Stéphanie Roussel, Cédric Pralet and Claude Cuiller

Abstract :

The concept of simultaneous engineering has been used for several years in the industry. However, it rarely aims to think the design of the product and the design of its industrial system (the factory) together. In this paper, we address the need to have a global view of architectural design and manufacturing throughout the entire design process. More precisely, we define a model-based approach which makes it possible to evaluate the impact of a product design on its manufacturability. This approach constitutes a first step, in a long-term perspective, to consider several high-level industrial systems and product designs together and choose the one that gives the best performances.

Paper 14 (Full Paper): Design Thinking and Acceptance Requirements for Designing Gamified Software.
Luca Piras, Daniele Dellagiacoma, Anna Perini, Angelo Susi, Paolo Giorgini and John Mylopoulos

Abstract :

Gamification is increasingly applied to engage people in performing tool-supported collaborative tasks. From previous experiences we learned that available gamification guidelines are not sufficient, and more importantly that motivational and acceptance aspects need to be considered when designing gamified software applications. To understand them, stakeholders need to be involved in the design process. This paper aims to (i) identify key requirements for designing gamified solutions, and ii) understand if existing methods (partially fitting those requirements) can be selected and combined to provide a comprehensive gamification design method. We discuss a set of key requirements for a suitable gamification design method. We illustrate how to select and combine existing methods to define a design approach that fits those requirements using Design Thinking and the Agon framework. Furthermore, we present a first empirical evaluation of the integrated design method, with participants including both requirements analysts and end-users of the gamified software. Our evaluation offers initial ideas towards a more general, systematic approach for gamification design.

Paper 47 (Short Paper): Bespoke: a Methodology to design Software Factories. A preliminary approach.
Maouaheb Belarbi and Vincent Englebert

Abstract :

Software Product Line (SPL) field is meant to engineer families of related products to reduce development cost. Leveraging feature models for capturing variable and common aspects inside of a product family omits crucial concepts that need to be considered through designing system domain perimeter. At this level, Model Driven Engineering was integrated in SPL to facilitate variability implementation and management. MDE techniques rely on the DSML meta-model that describes the main concepts of the domain and their relations which allow system designers to work closer to the system domain as they can manipulate real concepts.

Tutorial 2 :Towards Adaptive Enterprises using Digital Twins.
Authors: Vinay Kulkarni and Tony Clark.
Session chair: Estefanía Serral
Room 2

Abstract :

Modern enterprises are large complex systems operating in highly dynamic environments thus requiring to respond quickly to a variety of change drivers. Moreover, they are systems of systems wherein understanding is available in localized contexts only and that too is typically partial and uncertain. With the overall system behaviour hard to know a-priori and conventional techniques for system-wide analysis either lacking in rigour or defeated by the scale of the problem, the current practice often exclusively relies on human expertise for monitoring and adaptation. We outline a knowledge-guided simulation-aided data-driven model-based evidence-backed approach to make enterprises adaptive. The approach hinges on the concept of Digital Twin - a set of relevant models that are amenable to analysis and simulation. We describe the core modeling and model processing infrastructure developed, and early stage explorations of its application to problems where the mechanistic world view holds. We argue similar benefits are possible for problem spaces involving human actors as well.

Paper 12 (Full Paper): Reviewing the historical link between Business Process Management and IT: making the case towards digital innovation.
Tahir Ahmad and Amy Van Looy

Abstract :

Business Process Management (BPM) in the age of digitalization and globalization needs to become more innovative and creative. Information Technology (IT) helps to bring innovation in an organization’s business processes. Our research objective is to incorporate prior studies related to the co-evolution between BPM and IT in order to explore insights and innovation trends resulting from this IT integration in the BPM discipline. We position the sampled studies against three BPM frameworks (i.e. BPM life cycle components, BPM core elements, and BPM context factors) to better incorporate their historical link with (new) IT. A Systematic Literature Review (SLR) procedure was followed, resulting in 1,198 research papers for content analysis. The review output is summarized in a BPM-IT evolution chart and an extended BPM framework. The evolution chart confirms that Industry 4.0, Blockchains, Internet of Things (IoT) and Ambidextrous BPM are the most rising trends. We conclude by digging deeper into the novel themes for researchers, BPM consultants and managers.

Paper 16 (Short Paper): Exploring the Impact produced by an Industry 4.0 Transformation on Enterprise Architecture Models.
Elena Kornyshova and Judith Barrios Albornoz.

Abstract :

These days, organizations, especially industrial ones, are facing the impact of a new industrial revolution named Industry 4.0 (I4.0), which aims to change drastically the way organizations do business, interact with customers, manufacture their products and organize their production. To deal with these challenges, organizations continually adapt their enterprise models and renew their supporting Information Technology (IT). We focus on Enterprise Architecture (EA) models as a particular kind of enterprises models giving complete representations of enterprise components. Assuming that the organization has already developed its EA models, we aim to explore which components of EA models could be affected by an I4.0 transformation. In order to accomplish this research work, we selected TOGAF and RAMI4.0 as the most widespread frameworks of EA and I4.0 respectively. We compare these two frameworks for identifying a set of potential impact points. Our goal is to assist EA leaders while integrating the I4.0 components within the EA To-Be models.

Paper 20 (Full Paper): Business Process Ambidexterity and its impact on Business-IT alignment. A Systematic Literature Review.
Tomek Helbin and Amy Van Looy.

Abstract :

In the age of digital disruption, organizations face the growing need to both optimize existing processes, and to radically innovate and disrupt them. Business Process Management (BPM) has proven great value for process control and process optimization, however not for process disruption. Our Systematic Literature Review of Business Process Ambidexterity provides an overview of this nascent domain. In our research, we have divided all articles into two main strands of research, focusing on: (1) organizational capabilities enabling Business Process Ambidexterity, and (2) the actual dynamic balance between exploration and exploitation in BPM, which is enabled by the modelling and optimization stages in the business process lifecycle. As there is no widely accepted definition of Business Process Ambidexterity, we propose one for future use, based on the concept of paradoxical thinking. Business Process Ambidexterity may both enable, and be facilitated by digitalization; however, there is limited evidence that Business Process Ambidexterity enables Business-IT alignment. The main research gap is the lack of conceptual and practical guidelines on Business Process Ambidexterity implementation. Hence, this article encourages future research and provides preliminary guidance for practitioners.

Floren de Gier, Davy Kager, Stijn de Gouw and Tanja Vos.

Abstract :

To manage the complexity of today’s information systems, we need to investigate novel approaches for automated testing. In this paper we present two extensions to TESTAR, a state-of-the-art tool for testing systems through the GUI. We extend this tool with 1) a systematic and powerful approach for storing and querying test results through a graph database for offline oracles, and 2) support for accessibility evaluation of general applications for stakeholders with disabilities utilizing offline oracles. Furthermore, we conduct a preliminary validation of these extensions through a case study on the popular VLC Media Player.

Paper 57 (Full Paper): Fuzzy4U: A fuzzy logic system for user interfaces adaptation.
Tanguy Giuffrida, Sophie Dupuy-Chessa, Jean-Philippe Poli and Éric Céret.

Abstract :

Adapting User Interfaces to various technological devices is most often than not a part of human-computer interaction requirements. Although many studies addressed this topic some challenges remain, such as context uncertainty and combination of adaptation rules. This article represents an attempt at tackling these challenges, using fuzzy logic to handle adaptation. It proposes an architecture where an adaptation engine is supported by both fuzzy logic and Boolean logic, and illustrated by a prototype. The relevance of such approach has been studied through a theoretical comparison and an experiment including eight experts.

Paper 59 (Short Paper): A Unifying Reference Framework and Model for Adaptive Distributed Hybrid User Interfaces.
Audrey Sanctorum and Beat Signer.

Abstract :

Over the last decade, research on adaptive and distributed user interfaces (DUIs) has increased. We also witness a growing number of Internet of Things (IoT) devices, allowing digital user interfaces (UIs) to communicate with physical objects and vice versa through so-called hybrid user interfaces. There exist various solutions to manage adaptive, distributed or hybrid UIs. However, none of them covers all three aspects and users have to deal with multiple applications and configurations when developing adaptive distributed hybrid user interfaces. We introduce the eSPACE reference framework and conceptual model unifying the domains of adaptive, distributed and hybrid interfaces. While our reference framework has been inspired by the CAMELEON reference framework, the conceptual model is based on the Resource-Selector-Link (RSL) hypermedia metamodel. We propose an approach for adaptive distributed hybrid user interfaces where users can author their user interfaces based on the different levels of abstraction introduced by our reference framework. We further present a use case illustrating the extensibility, flexibility and reusability offered by our unified approach and discuss potential future work.

Keynote 2: Towards a Digital Business Operating System.
Prof. Jan Bosch, Chalmers University of Technology (Sweden)
Session chair: Yves Wautelet

Room 2215

Abstract :

We are living in the most exciting time in the history of mankind. The last century has seen unprecedented improvements in the quality of the human condition and technology is at the heart of this progress. Now we are experiencing an even bigger leap as we move towards a new level of digitalization and automation. Ranging from self-driving cars to factories without workers to societal infrastructure, every sensor and actuator is becoming connected and new applications that enable new opportunities are appearing daily. The fuel of this emerging connected, software-driven reality is software and the key challenge is to continuously deliver value to customers. The future of software business in this context is centered around four main developments: Speed, Data, Ecosystems and Empowerment. The focus on speed is concerned with the constantly increasing rate of deploying new software in the field. This continuous integration and deployment is no longer only the purview of internet companies but is also increasingly deployed in embedded systems. Second, data is concerned with the vast amounts of information collected from systems deployed in the field and the behavior of the users of these systems. Software businesses need to significantly improve their ability to exploit the value present in that data. Third, ecosystems are concerned with the transition in many companies from doing everything in-house to strategic use of innovation partners and partners providing commodity functionality. Finally, empowerment is concerned with addressing the challenges that traditional hierarchical forms of organization and the quest for alternative forms of organizing work based on empowerment and autonomy. The keynote addresses these four main developments, provides numerous examples from the Nordic and international industry and discusses the role of continuous integration, continuous deployment and devops in the transition from efficiency of software to effectiveness. It summarizes the next steps that industry and academia need to engage in to remain competitive.

Paper 33 (Short Paper): Executing IoT Processes in BPMN 2.0: Current Support and Remaining Challenges.
Faruk Hasić and Estefanía Serral.

Abstract :

The Internet of Things (IoT) has seen a vast surge in recent years, both in academia and in industry. Business processes are starting to take advantage of IoT to interact with the increasingly connected and dynamic physical environment. Recent literature has focused on analysing how this interaction between processes and IoT devices can be modelled, i.e. how the process can be described for discussion purposes. However, little attention is given to configuring the execution of these IoT-based processes. IoT-enhanced processes should indeed be able to incorporate IoT devices in the endeavour of process execution. This paper discusses research challenges in IoT process configuration and execution using the executable Business Process Model and Notation 2.0 (BPMN 2.0) standard. As such, we constitute an agenda for future research.

Paper 58 (Short Paper): Towards an integrated methodology for the development of blockchain-based solutions supporting cross-organizational processes.
Amaral de Sousa Victor and Burnay Corentin.

Abstract :

Blockchain technology is argued to have the potential to facilitate the development and improvement of cross-organizational business processes, on various aspects of the business process management discipline. In this paper, we review existing work on the use of blockchain technology to support business processes with a focus on cross-organizational settings. Based on this, we suggest to view blockchain as a software connector helping organizations to integrate the IT systems they use to support business processes. In addition, this paper suggests to use a model-driven engineering approach for the development of such connectors. By doing so, the need to develop a methodology helping to model and implement blockchain-based software connectors supporting crossorganizational business processes is highlighted. By adopting such an approach, organizations would be able to facilitate and speed up the development of blockchain-based solutions. This in turn would facilitate experimentations with this technology, which is considered as an important phase for organizations to derive value from it.

Paper 10 (Full Paper): Value Expression in Design Science Research.
Hans Weigand.

Abstract :

Design science research has grown into a major research approach in Information System (IS). Most current DSR approaches take a positivist approach that downplays human agency. An alternative framework is transformational design research (TDR), inspired by Rosenstock-Huessy’s view on language. This paper’s aim is to contribute to TDR by focusing on the expression of values, with a particular interest in values that are embodied in the technology. After a critical review of the traditional Requirement Engineering methods and of the so-called value-sensitive design approaches, we propose a new value expression approach that builds on and extends traditional value modelling. The method is illustrated with a literature example of process mining.

Paper 28 (Full Paper): Comparison of Two Value-Modeling Methods: e³value and SEAM.
Blagovesta Pirelli, Jaap Gordijn, Gil Regev and Alain Wegmann.

Abstract :

In the last few decades, several value-modeling methods have emerged in requirements engineering for IS research. We compare two value-modeling methods, e³value and SEAM. We illustrate their use with an example of the exchange of the Intellectual Property Rights (IPR) on music. In the process, we propose a comparison framework. The results of our study show that e3value and SEAM are similar value-modeling techniques: both model services in networked systems and focus on value exchanges. They differ, however, in the way value is conceptualized: the market viability of the service system in e3value versus the subjective value and lack of market profitability analysis in SEAM. e³value shows how value flows from one actor to another, whereas SEAM shows the relative importance of different value propositions and how they are constructed by the service network. These results can be used by modelers to select a value-modeling method for their purposes by proposing explicit selection criteria. The comparison framework, which is in its early stages of development, can be used to compare other modeling methods.

Keynote: Design Science Research
Speaker: Roel Wieringa
Session chairs: Fabian Gilson and Michaël Petit

Abstract :

The last ten years has seen a surge of interest in design science research in information systems, and of empirical research in software engineering. In this talk I present a framework for design science in information and software systems engineering that shows how in design science research, we iterate over designing new artifacts and empirically investigating these artifacts. To be relevant, the artifacts should potentially contribute to organizational goals, and to be empirically sound, research to validate new artifacts should provide insight into the effects of using these artifacts in an organizational context. The logic of both of these activities, design and empirical research, is that of rational decision making. I show how this logic can be used to structure our technical and empirical research goals and questions, as well as how to structure reports about our technical or empirical research. This gives us checklists for the design cycle used in technical research and for the empirical cycle used in empirical research.

Paper 2 (Short Paper): An Ontology for Representing and Annotating Data Flows to Facilitate Compliance Verification.
Christophe Debruyne, Jonathan Riggio, Olga De Troyer and Declan O’Sullivan.

Abstract :

In this paper we argue that there is a gap to be bridged between the development and maintenance of services and the various internal and external policies that emerge and evolve outside of these systems. To bridge this gap, we propose a semantic model, i.e. ontology, for representing Data Flows and linking them with structured representations of the data that is processed (datasets, databases, queries, etc.). Data Flow Diagramming is a technique for capturing the various data and information flows between an information system and external stakeholders as well as within such a system. This technique is used in the analysis phase of information systems development and captures the inputs and outputs of various processes. Our model allows these data flows to be presented and linked with structured representations of the data that is to be used, consulted, processed, etc. We demonstrate that this model can facilitate compliance verification processes of (intelligent) systems by allowing these flows to be analyzed. Next to the ontology, which has been made available according to best practices in the field, we furthermore posit our contributions within the state of the art.

Paper 15 (Full Paper): Ontology-Based Model Abstraction.
Giancarlo Guizzardi, Guylerme Figueiredo, Maria M. Hedblom and Geert Poels.

Abstract :

In recent years, there has been a growth in the use of reference conceptual models to capture information about complex and critical domains. However, as the complexity of domain increases, so does the size and complexity of the models that represent them. Over the years, different techniques for complexity management in large conceptual models have been developed. In particular, several authors have proposed different techniques for model abstraction. In this paper, we leverage on the ontologically well-founded semantics of the modeling language OntoUML to propose a novel approach for model abstraction in conceptual models. We provide a precise definition for a set of Graph-Rewriting rules that can automatically produce much-reduced versions of OntoUML models that concentrate the models’ information content around the ontologically essential types in that domain, i.e., the so-called Kinds. The approach has been implemented using a model-based editor and tested over a repository of OntoUML models.

Paper 18 (Full Paper): UMLto[No]SQL: Mapping Conceptual Schemas to Heterogeneous Datastores.
Gwendal Daniel, Abel Gómez and Jordi Cabot.

Abstract :

The growing need to store and manipulate large volumes of data has led to the blossoming of various families of data storage solutions. Software modelers can benefit from this growing diversity to improve critical parts of their applications, using a combination of different databases to store the data based on access, availability, and performance requirements. However, while the mapping of conceptual schemas to relational databases is a well-studied field of research, there are few works that target the role of conceptual modeling in a multiple and diverse data storage settings. This is particularly true when dealing with the mapping of constraints in the conceptual schema. In this paper we present the UMLto[No]SQL approach that maps conceptual schemas expressed in UML/OCL into a set of logical schemas (either relational or NoSQL ones) to be used to store the application data according to the data partition envisaged by the designer. Our mapping covers as well the database queries required to implement and check the model’s constraints. UMLto[No]SQL takes care of integrating the different data storages, and provides a modeling layer that enables a transparent manipulation of the data using conceptual level information.

Paper 32 (Short Paper): Problematic Attachment to Social Media: the Psychological States vs Usage Styles.
Majid Altuwairiqi, Emily Arden-Close, Nan Jiang, Georgina Powell and Raian Ali.

Abstract :

Many people worldwide rely on social media to satisfy their social needs for relatedness, learning and enhancing self-esteem. However, over-reliance on social media often results in problematic attachment, which risks personal, social and financial wellbeing. From a design perspective, we argue that social media can be improved with tools to manage such problematic attachment and help users reform their interaction style, social expectations and online identity to restore a healthy reliance. Designing such behaviour change tools can be challenging due to the characteristics of people with problematic behaviours, e.g. denial, relapse and cognitive dissonance. This paper explores the role of social media in such attachment and reveals associated psychological states. Our method provides an ecologically valid exploration through employing diary studies as a data collection method, aiming to introduce countermeasures for problematic attachment in future social media design.

Abstract :

Procrastination refers to a voluntary postponement that prevents people from performing their tasks and can hurt productivity and wellbeing. Procrastination might occur due to a lack of motivation to perform tasks or due to the low self-control that people might have over their time and task management. Social Networking Sites (hereafter SNS) are designed to enable their users to engage in online interaction for different purposes such as increasing popularity or exploring information. SNS embed influence and persuasion techniques to attract users which can make them a medium for procrastination where some users fail to maintain a desirable level of self-control over their usage. However, we argue that advances in persuasive technology and gamification techniques can be utilised to augment SMS and help users to regain self-control over their procrastination. Implementing these techniques correctly means that users can still enjoy accessing SNS while maintaining a desirable level of control over their procrastination. Building these anti-procrastination tools, however, is a challenging design activity due to their potential of triggering negative side-effects such as reactance and workarounds, and affecting the overall user experience. In this paper, we conduct user studies, consisting of an exploratory stage using focus groups, diary study and interviews and followed by a design stage based mainly on co-design sessions. Our studies’ participants self-declared having a problematic degree of procrastination on SNS, to explore procrastination countermeasure techniques that can augment the future designs of SNS and how best to apply them.

Paper 69 (Full Paper): Infoxication in the Genomic Data Era and Implications in the Development of Information Systems.
Ana León and Oscar Pastor.

Abstract :

We live in an age where data acquisition is no longer a problem and the real challenge is how to determine which information is the right one to take important and sometimes difficult decisions. Infoxication (also known as Infobesity or Information Overload) is a term used to describe the difficulty of adapting to new situations and effectively making decisions when there is too much information to manage. With the advent of the Big Data, infoxication is affecting critical domains such as Health Sciences, where tough decisions for patient’s health is being taken every day based on heterogeneous, unconnected and sometimes conflicting information. In order to understand the magnitude of the challenge, based on the information publicly available about the genetic causes of the disease and using data quality assessment techniques, we performed an exhaustive analysis of the DNA variations that have been associated to the risk of suffering migraine headache. The same analysis has been repeated 8 months after, and the results have allowed us to exemplify i) how fragile is the information in this domain, ii) the difficulty of finding repositories of contrasted and reliable data, and iii) the need to have information systems that, far from integrating and storing huge volumes of data, are able to support the decision-making process by providing mechanisms agile and flexible enough to be able to adapt to the changing user needs.

Paper 21: Investigating how Business Process Ambidexterity facilitates business-IT alignment in public sector organizations.
Tomek Helbin.

Abstract :

In today’s world of digital transformation and global hyper-competition the need for organizations to manage and innovate their Business Processes in both incremental and disruptive ways is greater than ever, both for private and public organizations. The nascent concept of Business Process Ambidexterity (balancing process exploitation and exploration) has been receiving a growing interest in the academia, and my research aims to address three research gaps: (1) the conceptualization of Business Process Ambidexterity and guidance on its implementation; (2) its impact on business-IT alignment, and (3) the specific contingency factors of Business Process Ambidexterity in the public sector. I will address these gaps through a research plan, covering a large-scale survey, extreme case research, Delphi study and design science research. At this stage I have completed a Systematic Literature Review of Business Process Ambidexterity, and I am preparing the next steps of my research.

Paper 17 (Full Paper): GDPR Compliance in the Design of the INFORM e-Learning Platform: a Case Study.
Evangelia Vanezi, Dimitrios Kouzapas, Georgia M. Kapitsaki, Theodora Costi, Alexandros Yeratziotis, Christos Mettouris, Anna Philippou and George A. Papadopoulos.

Abstract :

The European Union General Data Protection Regulation (GDPR) governs personal data processing, aiming to ensure privacy in all systems handling such data. All systems that process personal data, including software systems are legally obliged to comply to all articles of the GDPR applicable to them. In this paper, the case study of an e-Learning software platform, namely the INFORM platform and its compliance to relevant articles of the GDPR is presented. The e-Learning platform was developed with the objective to host the educational material developed under the JUSTICE EU-funded project INFORM, targeting judiciary, court staff and legal practitioners, in order to provide free and open distance access to the content. In particular, the paper demonstrates the compliance of the platform with the articles and principles of: Data Minimisation, Lawfulness of Processing, Right to Erasure, Right of Access, Right to Data Portability, Right to Rectification and Security of Processing. By applying these articles, conformance to the provision for Data Protection by design is also achieved; the platform’s software development process integrates the articles of the GDPR early in the development steps, from the specification and design phases. We show how the design process progressed and demonstrate the corresponding functionality within the e-Learning platform. The paper extracts a list of lessons learned and conclusions on software GDPR compliance.

Paper 44 (Full Paper): Towards a Prioritization of e-Government Challenges: an Exploratory Study in Belgium.
Hendrik Vandenberghe, Muriel Macken and Anthony Simonofski.

Abstract :

New developments in information and communica-tions technologies can enable governments to improve their inter-nal functioning as well as the services they offer to users. This transformation entails several hurdles that have been discussed extensively in existing literature. However, challenges are rarely ranked in terms of importance leaving practitioners in the dark regarding which one to tackle first. This paper analyzes, interlinks and prioritizes challenges that employees in federal, regional and local level experience in the further development of e(lectronic)-government in Belgium. Data was collected through six in-depth interviews and a focus group of three persons. The data was then analyzed following the Grounded Theory method. This allows to understand reasons for the relative lag Belgium has compared to countries leading the e-government charge.

The findings reveal that coordination and alignment issues (a lack of end-to-end thinking) constitute the main obstacle for Bel-gian governmental authorities regarding further e-government development. Finally, current policies are reviewed to search for possible leads for solutions for the challenges discussed. This paper contributes to existing research in e-government, by explicitly dis-tinguishing crucial challenges and ranking them on importance. This allows both researchers and practitioners to focus on focusing on the most important hurdles to further development.

Paper 45 (Full Paper): The Impact of Impediments on Open Government Data Use: Insights from Users.
Jonathan Crusoe, Anthony Simonofski, Antoine Clarinval and Elisabeth Gebka.

Abstract :

Open Government Data (OGD) is interoperable data that is published on the Internet by public organizations and can be freely used and redistributed by users. OGD is expected to result in several benefits, such as innovative products and services, collective problem solving, and equal access to information. However, several impediments complicate the realization of the benefits. These impediments can impact the process of using OGD that consists of the four phases: motivation, search and evaluate, access and prepare, and aggregate and transform. In this paper, we examine the case of a data science project conducted by master’s students to understand how impediments impact their use. In order to study this case, we use a mixedmethod approach combining a questionnaire sent to the 30 students and nine in-depth interviews. The analysis of the data allowed us to identify and discuss the impact of several impediments on use, such as difficulties in finding an idea and the lack of longitudinal data. Subsequently, we were able to give recommendations to publishers to improve their OGD portals, infrastructure, and data as well as opening up research directions in the OGD field.

Paper 22 (Full Paper): Towards a Software Sustainability-Quality Model: Insights from a Multi-Case Study.
Nelly Condori-Fernández and Patricia Lago.

Abstract :

Background. Software sustainability is defined in terms of multiple and interdependent dimensions (economic, social, technical and environmental). Preliminary initiatives have investigated the contribution of certain quality attributes to sustainability dimensions. Problem. Despite these valuable efforts, the characterization of software sustainability is still a key challenge. This entails how sustainability can be embraced in the design of software systems by identifying the relevant software quality attributes (QAs) and their dependencies. Both attributes and dependencies vary heavily with amongst others the type of software system and its operational context. Aim and Method. We followed a multiple case study research method with the main objective ofinvestigating the applicability of the sustainability model in different contexts. We aim also to enrich our model, by means of identifying missing quality attributes or new contributions to the sustainability dimensions. We selected two software projects as cases of our study, where each one was independently conducted in specific situations. Results. The results of the study show that the relevant quality requirements identified in both projects (cases) are covered by most of the QAs related to the social (82%) and technical (83%) dimensions. Moreover, some QAs that were not addressed in the corresponding projects, their relevance like context completeness, and flexibility were acknowledged. These results suggest that the software sustainability model could support the identification of relevant QAs. The case study also contributed to identify QAs that had not been considered in the economic, technical and social dimensions of the sustainability-quality model.

Paper 41 (Short Paper): A Nichesourcing Framework applied to Software Sustainability Requirements.
Nelly Condori-Fernández, Patricia Lago, Miguel R. Luaces and Alejandro Catala.

Abstract :

Background A software sustainability model is commonly defined in terms of social, economic, technical and environmental dimensions. A key challenge is its characterization regarding sustainability requirements and their dependencies since it depends on, and varies with, the type of software system, and changes in operational contexts. [Aims] With the purpose of facilitating the definition of a context-dependent software sustainability model, we introduce nichesourcing as a type of distributed problem-solving paradigm, named crowdsourcing. Method First a set of nichesourcing requirements were identified, and an existing nichesourcing methodology, originally used in the cultural heritage domain was analyzed with respect to its applicability in Software Engineering. Results As a result, we propose an adapted methodology for nichesourcing the knowledge on sustainability requirements and their dependencies. Strengths and challenges for crowdsourced software engineering are also identified.

Paper 91 (Full Paper): Model-driven engineering support for social and environmental accounting.
Sergio España, Niels Bik and Sietse Overbeek.

Abstract :

Social and environmental accounting (SEA) is becoming commonplace in organisations that want to assess and report on their business ethics and sustainability performance. While there is an abundance of methods and standards that define how to perform such practice, tool support is much more limited and does not fully match the needs of organisations. In this paper, we present a model-driven engineering approach to support SEA. We are engineering a domain-specific language that allows creating models of SEA methods and we are implementing a tool that interprets such models at runtime, effectively supporting the accounting, and providing basic model management operations. This paper presents the preliminary results and, as a running example, we use UniSAF, a SEA method to assess the sustainability of universities. The results are promising, according to two SEA experts we have consulted, and have triggered the interest of the Fair Trade Software Foundation.

Paper 81: A Green-by-Design Methodology to Increase Sustainability of Smart City Systems.
Adrien Voisin.

Abstract :

Smart Cities are increasingly cited as a solution to decrease CO₂ emissions within cities. However, the technology that supports Smart City systems may in turn cause direct, indirect and rebound environmental impacts, including greenhouse gas emissions. Recent studies assessing the positive environmental impact of Information and Communication Technology (ICT) tend to focus on direct effects, thus giving little attention to indirect and especially rebound effects. The goal of our thesis is to propose an evaluation methodology to assist Smart City systems designers in assessing all possible environmental impacts of candidate Smart City systems designs. To design and validate the proposed methodology, the research scope will be narrowed on a subcategory of Smart City systems, chosen according to its relevance in terms of risk to produce rebound effects. The research process will follow the guidelines defined by Wieringa for conducting design science in ICT.

Paper 101: Towards personalized feedback in a smart learning environment for teaching conceptual modelling.
Daria Bogdanova.

Abstract :

Conceptual modelling is one of the most challenging areas of learning in software or enterprise engineering education. Building this complex skill requires tremendous efforts and amounts of elaborative feedback from the teacher, especially in the case of novice modelers. However, the growing numbers of students wishing to pursue degrees requiring conceptual modelling as an integral skill make sufficient personalized feedback an unreachable goal for educators. The situation is aggravated by the lack of a universal, commonly accepted educational framework for conceptual modelling, which could serve as a basis for learning material and feedback development. In this paper, the steps towards the development of feedback architecture of a smart learning environment for conceptual modelling are presented, along with the intermediate results of the research project. The steps include the development of learning ontology for conceptual data modelling, implementation of CaMeLOT educational framework and the learning ontology for providing personalized feedback and finding the appropriate feedback timing.

Keynote 3 : Towards Cross-Media Information Spaces and Architectures.
Prof. Beat Signer, Vrije Universiteit Brussel (Belgium)
Session chair: Jean Vanderdonckt

Room 2215

Abstract :

The efficient management and retrieval of information has been investigated since the early days of Vannevar Bush's seminal article 'As We May Think' introducing the Memex. However, nowadays information is fragmented across different media types, devices as well as digital and physical environments and we are often struggling to find information. In this keynote I will discuss three main issues to be addressed when developing solutions for managing information in these co-called cross-media information spaces. We first have a look at an extensible cross-media linking solution based on the RSL (resource-selector-link) hypermedia metamodel where information can be integrated across applications, devices as well as digital and physical information environments. I will then outline some of the limitations of existing digital document formats which are often just a simulation of paper documents and their affordances on desktop computers, and discuss more flexible document representations for cross-media information spaces. Further, new forms of human-information interaction and cross-media user interfaces, including some recent work on dynamic data physicalisation, are introduced. Various research artefacts such as the EdFest interactive paper prototype, the PimVis solution for personal cross-media information management or the MindXpres platform for next generation presentation solutions will be used to illustrate different aspects of the presented data-centric approach for cross-media information spaces and architectures. Last but not least, I will provide an outlook on how the embedding of the presented concepts at the level of an operating system might ultimately lead to new possibilities for cross-media information management and innovative forms of human-information interaction.

Paper 6 (Short Paper): Supporting Journalistic News Angles with Models and Analogies.
Bjørnar Tessem and Andreas L Opdahl.

Abstract :

News angles are approaches to content presentation in journalism, where the journalist chooses which facts of an event to present. The News Angler project investigates how to computationally support the creation and selection of original news angles for a news event based on information from big data sources. At least two creative approaches are possible. One is to maintain a library of well-known news angles represented in a suitable modeling language, matching published reports on a current event to news angles in order to identify possible angles that have not yet been used. A second approach is not to represent news angles explicitly, instead matching the current event with previous events, and transferring angles from past to present reports by similarity and analogy. Both approaches are described and technologies needed to proceed in either direction are discussed.

Paper 19 (Short Paper): Correlation between textual similarity and quality of LDA topic model results.
Amaury Delamaire, Mihaela Juganaru-Mathieu and Michel Beigbeder.

Abstract :

The LDA topic model describes a corpus on the basis of its vocabulary. Our experiment aims at determining whether LDA outputs’ quality can be estimated through text similarity metrics, and if so determining the most relevant one. To do so, we use a categorized corpus on which we apply these metrics on every pair of categories. We present correlation scores between several metrics and the quality of the topic model. The experiments also include a comparison between simple and complex term extraction within our framework. We observed very high correlations with the Hellinger distance with or without complex terms, while the Soergel distance is most efficient when including complex terms. These experiments are a case study on a categorised corpus of 20,000 article abstracts.

Paper 24 (Short Paper): Identifying sound descriptions in written documents.
Suzanne Mpouli, Christine Largeron and Michel Beigbeder.

Abstract :

Automatically identifying sound descriptions can be useful to extract soundscapes from written documents. In this respect, we present a preliminary work on the identification of sound descriptions which first expands a list of sound terms taken from a machine-readable lexical resource. Then, to find out the producer of each sound mentioned in a text collection, two methods have been tested out: one which relies on dependency parsing and the other which uses a pre-trained word embedding model. Both methods have been evaluated on a set of sentences extracted from three 19th century French novels; the obtained results suggest that dependency parsing performs better on this specific task. It should be noted that the first step of the proposed system is domain-independent and can generate a domain-specific lexicon for any topic.

Tutorial 3: Using 4C/ID for Teaching Conceptual Modeling.
Author: Daria Bogdanova.
Session chair: Stephan Poelmans
Room 2

Abstract :

The acquisition of conceptual modelling skills is a complex learning task: a business analyst or functional analyst must have the necessary knowledge of different modelling techniques (eg. UML class diagrams, Use Case diagrams, state charts, BPMN), the ability of abstract thinking so as to think in terms of concepts rather than of concrete objects and skills to correctly analyze requirements, distilling concepts from them, and converting these to a correct model. Part of the difficulties of learning conceptual modelling result from the fact that multiple good solutions exist for a single problem, and each of these solutions may have different advantages and disadvantages. The learning process therefore requires a lot of exercising, supported by individual feedback from the teacher. Moreover, the ill-structured nature of the problems calls for detailed and elaborative rather than merely corrective feedback. Heterogeneous groups of students make the educators’ task even more challenging as students typically learn at different paces.

The acquisition of conceptual modelling skills is a complex learning task: a business analyst or functional analyst must have the necessary knowledge of different modelling techniques (eg.

Part of the difficulties of learning conceptual modelling result from the fact that multiple good solutions exist for a single problem, and each of these solutions may have different advantages and disadvantages. The learning process therefore requires a lot of exercising, supported by individual feedback from the teacher. Moreover, the ill-structured nature of the problems calls for detailed and elaborative rather than merely corrective feedback. Heterogeneous groups of students make the educators’ task even more challenging as students typically learn at different paces.

To tackle these problems, the LIRIS research centre developed a modelling method (MERODE) that provides the learners with clear criteria on how to address the modelling problem, and what criteria to use to assess a model's quality. The method is supported by a didactic modelling and simulation tool (JMermaid/MERLIN). It helps junior modellers to form a concrete representation of the information system that will result from their model. JMermaid and MERLIN also support the learner by giving feedback during the modelling and simulation process.

Despite the support of such didactic tool, student still have the need for a phased learning trajectory that allows students learning at their individual pace. We addressed this need by developing a blended learning course based on the instructional design method 4C/ID (introduced by J. van Merrienboer).

This tutorial reviews the development of this course. We start with a brief introduction to the 4C/ID model. Then for each of its components (learning tasks, supportive information, part-task practice and just-in-time information), we let the participants reflect on how to apply the concepts for designing a conceptual learning environment or course, and then explain how we applied it in our course while making used of the edX platform. In particular, we explain how exercises are developed as whole tasks with decreasing learner support. We report about an experiment that measured the impact of introducing "part-task practice" on students' ability to solve more complex exercises and explain how personalized feedback can be provided for such tasks.

Finally, student's behaviour has been studied based on log-data from the environment. We also report how the better and worse students display different behaviour in their use of the learning environment.
