    Abstract
    Am Beispiel der Knochenmarktransplantation, eines medizinischen Spezialgebietes, wird im folgenden dargelegt, wie man BenutzerInnen eine großen Teil des Aufwandes bei der Wissensbeschaffung abnehmen kann, indem man Suchergebnisse aus dem Netz fragebezogen zusammenfaßt. Dadurch wird in zeitkritischen Situationen, wie sie in Diagnose und Therapie alltäglich sind, die Aufnahme neuen Wissens ermöglicht. Auf einen Überblick über den Stand des Textzusammenfassens und der Ontologieentwicklung folgt eine Systemskizze, in der die Informationssuche im WWW durch ein kognitiv fundiertes Zusammenfassungssystem ergänzt wird. Dazu wird eine Fach-Ontologie vorgeschlagen, die das benötigte Wissen organisiert und repräsentiert.

    Abstract
    Faceted Knowledge Representation provides a formalism for implementing knowledge systems. The basic notions of faceted knowledge representation are "unit", "relation", "facet" and "interpretation". Units are atomic elements and can be abstract elements or refer to external objects in an application. Relations are sequences or matrices of 0 and 1's (binary matrices). Facets are relational structures that combine units and relations. Each facet represents an aspect or viewpoint of a knowledge system. Interpretations are mappings that can be used to translate between different representations. This paper introduces the basic notions of faceted knowledge representation. The formalism is applied here to an abstract modeling of a faceted thesaurus as used in information retrieval.

    Abstract
    Information Systems (IS) is among the most widespread terms in the Computer Science field but a well founded, widely accepted theory of IS is still missing. With the Internet publication of the FRISCO report, the IFIP task group "FRamework of Information System COncepts" has taken a first step towards such a theory. Among the major achievements of this report are: (1) it builds on a solid basis formed by semiotics and ontology, (2) it defines a compendium of about 100 core IS concepts in a coherent and consistent way, (3) it goes beyond the common narrow view of information systems as pure technical artefacts by adopting an interdisciplinary, socio-technical view on them. In the autumn of 1999, a first review of the report and its impact was undertaken at the ISCO-4 conference in Leiden. In a workshop specifically devoted to the subject, the original aims and goals of FRISCO were confirmed to be still valid and the overall approach and achievements of the report were acknowledged. On the other hand, the workshop revealed some misconceptions, errors and weaknesses of the report in its present form, which are to be removed through a comprehensive revision now under way. This paper reports on the results of the Leiden conference and the current revision activities. It also points out some important consequences of the FRISCO approach as a whole.
