- 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
- The term "facet" was introduced into the field of library classification systems by Ranganathan in the 1930's [Ranganathan, 1962]. A facet is a viewpoint or aspect. In contrast to traditional classification systems, faceted systems are modular in that a domain is analyzed in terms of baseline facets which are then synthesized. In this paper, the term "facet" is used in a broader meaning. Facets can describe different aspects on the same level of abstraction or the same aspect on different levels of abstraction. The notion of facets is related to database views, multicontexts and conceptual scaling in formal concept analysis [Ganter and Wille, 1999], polymorphism in object-oriented design, aspect-oriented programming, views and contexts in description logic and semantic networks. This paper presents a definition of facets in terms of faceted knowledge representation that incorporates the traditional narrower notion of facets and potentially facilitates translation between different knowledge representation formalisms. A goal of this approach is a modular, machine-aided knowledge base design mechanism. A possible application is faceted thesaurus construction for information retrieval and data mining. Reasoning complexity depends on the size of the modules (facets). A more general analysis of complexity will be left for future research.

- Abstract
- Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln

- Abstract
- Document retrieval is a highly interactive process dealing with large amounts of information. Visual representations can provide both a means for managing the complexity of large information structures and an interface style well suited to interactive manipulation. The system we have designed utilizes visually displayed graphic structures and a direct manipulation interface style to supply an integrated environment for retrieval. A common visually displayed network structure is used for query, document content, and term relations. A query can be modified through direct manipulation of its visual form by incorporating terms from any other information structure the system displays. An associative thesaurus of terms and an inter-document network provide information about a document collection that can complement other retrieval aids. Visualization of these large data structures makes use of fisheye views and overview diagrams to help overcome some of the inherent difficulties of orientation and navigation in large information structures.

- Abstract
- Information retrieval over the Internet increasingly requires the filtering of thousands of heterogeneous information sources. Important sources of information include not only traditional databases with structured data and queries, but also increasing numbers of non-traditional, semi- or unstructured collections such as Web sites, FTP archives, etc. As the number and variability of sources increases, new ways of automatically summarizing, discovering, and selecting collections relevant to a user's query are needed. One such method involves the use of classification schemes, such as the Library of Congress Classification (LCC) [10], within which a collection may be represented based on its content, irrespective of the structure of the actual data or documents. For such a system to be useful in a large-scale distributed environment, it must be easy to use for both collection managers and users. As a result, it must be possible to classify documents automatically within a classification scheme. Furthermore, there must be a straightforward and intuitive interface with which the user may use the scheme to assist in information retrieval (IR).

- 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.

- Abstract
- For digital information systems' design to continue to flourish, it would appear that we may need to incorporate a view of the social in our design efforts. While there are a variety of disciplines and viewpoints within the social sciences which might assist information system designers in an effort to achieve a wider perspective in design, the remainder of this paper will focus on one that seems particularly well-suited for this role, the sociology of knowledge
