    Semantic Navigation Maps for Information Agents in Environment Information Systems
    (Umweltinformatik ’99 - Umweltinformatik zwischen Theorie und Industrieanwendung, 1999) Benn, Wolfgang; Beyrich, Günther; Görlitz, Otmar
    The automated retrieval of information in Environment Information Systems by information agents is severely hindered by the heterogeneity of these systems. For the decision if an information is a relevant answer to a query, information agents need to understand semantics and context of the query. In this paper we propose our concept of describing and exploiting contextual relations in the domain of environment information on the base of Kohonen’s self-organizing feature maps. We apply this concept for the automated semantic classification of query results into an existing knowledge space. Using this technique, information agents can be endowed with domain knowledge. Thus they are enabled to retrieve information in heterogeneous Environment Information Systems matching the context of the query.

    Zugriff auf Datenbanken über das World Wide Web
    (Informatik-Spektrum: Vol. 21, No. 1, 1998) Benn, Wolfgang; Gringer, Ingo
      Datenbanksysteme gewinnen für das World Wide Web (WWW) zunehmend an Bedeutung, da sie die Organisation großer Informationsmengen sowie die transaktionsbasierte und sichere Verwaltung von Daten und Geschäftsvorgängen unterstützen. Um effizient auf Datenbanksysteme (DBS) in Internetanwendungen zugreifen zu können, müssen geeignete Übergänge zwischen WWW und DBS benutzt werden. Wir stellen anhand eines Forderungskatalogs die Eigenschaften aktueller Verfahren vor, ordnen sie den Architekturen der Informationsverarbeitung zu und diskutieren die Möglichkeiten weiterer Entwicklungen.Summary  The importance of Database Systems (DBS) for the World Wide Web (WWW) is increasing significantly, because they do not only support the organization of large amounts of information but also the transaction-based and secure management of data and business processes. In order to access database systems from Internet applications efficiently, appropriate transitions between WWW and DBS have to be applied. By means of a catalogue of demands, we will present the features of current methods, assign them to corresponding architectures of information processing and discuss the possibilities of further developments.
