    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.

    From scenarios to KCPM dynamic schemas: Aspects of automatic mapping
    (Natural language processing and information systems, 2003) Fliedl, Günther; Kop, Christian; Mayr, Heinrich C.
    Scenarios are a very popular means for describing and analyzing behavioral aspects on the level of natural language. In information systems design, they form the basis for a subsequent step of conceptual dynamic modeling. To enhance this step, linguistic instruments prove applicable for transforming scenarios into conceptual schemas of various models. This transformation usually consists of three steps: linguistic analysis, component mapping and schema construction. Within this paper we investigate to which extent these steps may be performed automatically in the framework of KCPM, a conceptual predesign model which is used as an Interlingua between natural language and arbitrary conceptual models.

    OBSE – an approach to Ontology-based Software Engineering in the practice
    (Enterprise modelling and information systems architectures – concepts and applications, 2007) Bachmann, Andrej; Hesse, Wolfgang; Russ, Aaron; Kop, Christian; Mayr, Heinrich C.; Vöhringer, Jürgen
    In this article we present a new approach to Ontology-based Software Engineering (OBSE) meant for practical use in enterprises and industrial projects. Following this approach, Software projects are no longer driven only by requirements and models but also by one or several ontology/ies covering their application domain. Our main thesis says that OBSE can offer similar opportunities and benefits for re-engineering and re-use in the early phases of software development as object orientation does for the later ones. OBSE is to be supported by tools which integrate ontologies in the SE process. A prototype of such a tool – based on the KCPM and EOS methodologies – is presently being developed in a joint project of our groups.

    Tool supported extraction of behavior models
    (Information systems technology and its applications, ISTA' 2005, 2005) Kop, Christian; Vöhringer, Jürgen; Hölbling, Martin; Horn, Thomas; Mayr, Heinrich C.; Irrasch, Christian
    Information system projects often suffer from incomplete or inadequate requirements specifications. In our opinion, which is supported by practical experience, these problems result from the fact that the models usually applied for requirements analysis are to abstract as to be easily understood and validated by the business owners, i.e. the end users. In addition to that, validation is often hampered by the fact that traditional modeling approaches do not relate the particular model elements to their corresponding requirements sources. We, therefore, propose an approach that uses a lean and thus more transparent requirements model, which is intermediate in the sense that it has to be mapped, after validation, to one of the traditional conceptual models. Clearly introducing such an additional step into the information system development process induces increased effort which has to be reduced by appropriate tool support. This paper concentrates on specific aspects and tool support for extracting behavior models out of requirements texts.

    A user centered approach to requirements modeling
    (Modellierung 2002, Modellierung in der Praxis – Modellierung für die Praxis, 2002) Mayr, Heinrich C.; Kop, Christian
    The paper argues that the conventional methods for object oriented analysis and conceptual modeling suffer from lacks in requirements elicitation and validation by the end-user. Therefore, an intermediate level called 'conceptual predesign' is introduced between natural language requirements specification and conceptual design. The paper introduces the basic notions of a conceptual predesign model and discusses heuristic rules for their automatic mapping to the conceptual level, e.g. to UML.
