    Application Engineering Research at Universität Klagenfurt
    (40 Years EMISA 2019, 2020) Mayr, Heinrich C.; Paczona, Martin; Shekhovtsov, Vladimir A.
    We sketch here the general orientation (“Mission”) and the recent research projects of our research group, which is part of the Institute of Applied Informatics in the Faculty of Technical Sciences. In research and teaching, we address human centered research in (1) model engineering: user centered (requirements) modeling languages that are intuitively to understand, apply and validate, (2) design and realization of user-oriented application architectures with a strong focus on the integration of user needs into the development process, and (3) customer centered, accessible, effective and sustainable software and services.

    Aspectual predesign: extending KCPM to map non-functional requirements
    (Information systems technology and its applications, ISTA' 2005, 2005) Shekhovtsov, Vladimir A.; Kostanyan, Arkady V.
    This paper presents an extension of the Klagenfurt Conceptual Predesign Model (KCPM) allowing taking into account the non-functional requirements to the system. These requirements are treated as crosscutting concerns. This process could be also seen as an addition to the AOSD paradigm that brings the gap between the Aspect-Oriented Requirement Engineering and Aspect-Oriented Modeling. The extensions of the KCPM schema and the new mapping rules are introduced for the case of asymmetric AOSD approach.

    Capturing the Semantics of Quality Requirements into an Intermediate Predesign Model
    (SIGSAND-EUROPE 2008: Proceedings of the Third AIS SIGSAND European Symposium on Analysis, Design, Use and Societal Impact of Information Systems, 2008) Shekhovtsov, Vladimir A.; Kop, Christian; Mayr, Heinrich C.
    We present an approach to capturing the semantics of quality requirements in an intermediate predesign step residing between quality requirements elicitation and conceptual design. We propose Quality-Aware Predesign Model (QAPM) to be used at this step. In this model, the problem domain is viewed as a set of concerns. Out of this set, concerns related to quality are separated from those related to the main functionality of the system. Quality concerns are represented by hierarchical quality models incorporating quality characteristics and indicators. The semantics of both functional and quality concerns is modeled using Klagenfurt Conceptual Predesign Model (KCPM) concepts with necessary modifications. On basis of this, QAPM offers the set of concepts to represent the semantics of cross- cutting relationships between the concerns.

    Constructing POSE: A Tool for Eliciting Quality Requirements
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Shekhovtsov, Vladimir A.; Kaschek, Roland; Zlatkin, Sergiy
    Quality requirements elicitation for new computer applications rests traditionally on interviewing stakeholders. That makes getting these requirements right more complicated than is necessary because the anticipated users not necessarily are good at talking about the kind of computer aid and its qualities they would appreciate. We suggest bypassing that problem by constructing and using POSE (parameterized online simulation environment). Within this environment, anticipated users can explore ways of computer support for their work; it then makes it easier to talk about a potential computerized aid and the qualities thereof. Using POSE also simplifies obtaining quantified scenarios related to the various system qualities. As a result, this environment aids in getting the quality requirements right.

    Tool supported aspectual predesign
    (Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Shekhovtsov, Vladimir A.; Kostanyan, Arkadiy V.; Gritskov, Eugene; Litvinenko, Yury
    Aspectual predesign is an approach to user-verified mapping of the nonfunctional requirements to the system into the aspect-oriented design model. It is an extension of the Klagenfurt Conceptual Predesign. In this paper, we present the architecture of modular software tool aiming to support the aspectual predesign workflow. The XML-based Predesign Exchange Format (PEF) for conversionindependent representation of aspectual predesign model (APM) is introduced.

    Towards Entropy-Based Requirements Elicitation
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Kostanyan, Arkadiy V.; Shekhovtsov, Vladimir A.
    This paper presents our views towards constructing the universal parsing technique for the software requirements texts and the requirements elicitation technique based on the output of this parsing process. With the proposed parsing technique, it should be possible to achieve language-independent processing of the requirements texts. Source sentences are treated as systems with words as elements and with a state determining the set of links between elements. The main goal of the parser is to find the state of the system with the highest organization level by minimizing its entropy. The requirements elicitation technique extends trained indicator approach by Cleland-Huang treating inter-word links as indicators. The output of the elicitation process is the set of requirements information ready to be processed further using Conceptual and Aspectual Predesign techniques.

    Towards selecting among business process modeling methodologies
    (Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Kaschek, Roland; Pavlov, Roman; Shekhovtsov, Vladimir A.; Zlatkin, Sergiy
    The problem of selecting the business process modeling methodology best suited for the business process modeling task at hand is often hampered by the conditions under which the selection is made. In this paper we sketch the foundations of a framework for selecting business process modeling methods. We base this framework on the Analytic Hierarchy Process. We therefore use a hierarchy of characteristics of business process modeling methodologies for our selection approach. To demonstrate how our approach works we discuss its application to two business process modeling tasks. We have developed a software tool that implements our framework. We describe this tool briefly in this paper.

    View harmonization in software processes: from the idea to QuASE
    (Informatik 2016, 2016) Shekhovtsov, Vladimir A.; Mayr, Heinrich C.
    Quality assurance in software processes requires that the involved parties share acommon understanding of the requirements to be addressed. As a result, a central aspect ofQuality-Aware Software Engineering (QuASE) is to harmonize the stakeholder views in systemdevelopment. The paper shows how our approach to QuASE evolved from the initial idea to acomplete software system supporting mutual understanding of communicated information: thissystem not only provides a comprehensive set of understandability management techniques butalso integrates knowledge from different ticketing systems.
