    SUPPORTING TERMINOLOGICAL STANDARDIZATION IN CONCEPTUAL MODELS - A PLUGIN FOR A META-MODELLING TOOL

    TodayÂŽs enterprises are accumulating huge repositories of conceptual models, such as data models, organisational charts and most notably business process models. Those models often grow heterogeneously with the company and are thus often terminologically divers and complex. This terminological diversity originates from the fact that natural language allows an issu to be described in a large variety of ways especially when many modellers are involved. This diversity can become a pitfall when conceptual models are subject to model analysis techniqus, which require terminologically comparable model elements. Therefore, it is essential to ensure model quality by enforcing naming conventions. This paper introduces a prototype, which intends to resolve all associated issus of terminological standardisation already during the modelling phase or ex-post based on existing models. The modeller is guided through the standardization process by providing an automated list of all correct phrase propositions according to his entered phrase. In this approach, naming conventions can easily be defined and enforced. This leads to terminologically unambiguous conceptual models, which are easier to understand and ready for further analysis purposes

    Evaluation ausgewÀhlter BPMN 2.0 Werkzeuge

    Die Modellierung von GeschĂ€ftsprozessen mittels der etablierten Modellierungssprache Business Process Management and Notation, kurz BPMN, gewinnt immer mehr Bedeutung. Mittels BPMN werden UnternehmensablĂ€ufe nicht nur grafisch modelliert, sondern lassen sich auch analysieren und optimieren. FĂŒr die Modellierung von GeschĂ€ftsprozessen gibt es eine große Anzahl von Modellierungstools. Doch welches BPMN-Modelliertools ist am effektivsten, effizientesten und zufriedenstellendsten? Die Antwort auf diese Frage ist nicht einfach. Denn bisher gibt es kaum etablierte Kriterien, anhand dessen man bewerten kann, welches Tool welche Eigenschaften oder Funktionen am besten erfĂŒllt. Diese Arbeit beschĂ€ftigt sich mit dieser Fragestellung. Um einen Fokus zu setzen, werden Kriterien definiert, mittels denen sich fĂŒr (ausgewĂ€hlte) BPMN-Modellierungswerkzeuge der Grad der Usability, d.h. Benutzbarkeit, bewerten lĂ€sst. ZunĂ€chst wird eine Long List erstellt, die alle auf dem Markt zur VerfĂŒgung stehenden BPMN-Tools umfasst. Anschließend wird aus der Long eine Short List gebildet. Die in dieser Short List enthaltenen BPMN-Tools werden jeweils kurz vorgestellt und mittels aufgestellten Usability-Kriterien bewertet. Die Ergebnisse werden dann in Form von Tabellen dargestellt sowie die Tools systematisch miteinander verglichen. Um eine bessere Vergleichbarkeit der Tools zu erzielen, wird derselbe GeschĂ€ftsprozess aus dem universitĂ€ren Umfeld mit allen BPMN-Tools aus der Short List modelliert

    Geo-Ontology Tools – the missing link

    Full text link
    Numerous authors have presented ontology building tools that have all been developed as part of academic projects and that are usually adaptations of more generic tools for geo-spatial applications. While we trust that these tools do their job for the special purpose they have been built, the GIScience user community is still a long way away from off-the-shelf ontology builders that can be used by GIS project managers. In this article, we present a comparative study of ontology building tools described in some twenty peer-reviewed GIScience journal articles. We analyze them from the perspective of two application domains, crime analysis and transportation/land use. For the latter, we developed a database schema, which is substantially different from the three main templates commonly used. The crime analysis application uses a rule base for an agent-based model that had no precursor. In both cases, the currently available set of tools cannot replace manual coding of ontologies for use with ESRI-based application software. Based on these experiences, we outline a requirements list of what the tools described in the first part of the article are missing to make them practical from an applications perspective. The result is an R&D agenda for this important aspect of GIScience
