    Abstract
    Reports text information retrieval experiments performed as part of the 3 rd round of Text Retrieval Conferences (TREC) using the Okapi online catalogue system at City University, UK. The emphasis in TREC-3 was: further refinement of term weighting functions; an investigation of run time passage determination and searching; expansion of ad hoc queries by terms extracted from the top documents retrieved by a trial search; new methods for choosing query expansion terms after relevance feedback, now split into methods of ranking terms prior to selection and subsequent selection procedures; and the development of a user interface procedure within the new TREC interactive search framework

    Abstract
    Begriffliche Datensysteme sind im Rahmen der Formalen Begriffsanalyse entstanden und gründen sich auf mathematische Formalisierungen von Begriff, Begriffssystem und Begriffliche Datei. Sie machen Wissen, das in einer Datenbasis vorliegt, begrifflich zugänglich und interpretierbar. Hierfür werden begriffliche Zusammenhänge entsprechend gewählter Frageaspekte in gestuften Liniendiagrammen dargestellt. Durch Verfeinern, Vergröbern und Wechseln von Begriffstrukturen kann man unbegrenzt durch das in der Datenbasis gespeicherte Wissen "navigieren". In einem Forschungsprojekt, gefördert vom Zentrum für interdisziplinäre Technikforschung an der TH Darmstadt, ist ein Prototyp eines begrifflichen Datensystems erstellt worden, dem als Datenkontext eine ausgewählte, begrifflich aufgearbeitete Menge von Büchern zur interdisziplinären Technikforschung zugrunde liegt. Mit diesem Prototyp soll die flexible und variable Verwendung begrifflicher datensysteme im Literaturbereich demonstriert werden

    TOSCANA ist ein Computerprogramm, mit dem begriffliche Erkundungssysteme auf der Grundlage der Formalen Begriffsanalyse erstellt werden können.In der vorliegenden Arbeit wird diskutiert, wie TOSCANA zur bibliothekarischen Sacherschließung und thematischen Literatursuche eingesetzt werden kann. Berichtet wird dabei von dem Forschungsprojekt 'Anwendung eines Modells begrifflicher Wissenssysteme im Bereich der Literatur zur interdisziplinären Technikforschung', das vom Darmstädter Zentrum für interdisziplinäre Technikforschung gefördert worden ist

    Abstract
    Mechanistisches Denken und seine maschinelle Umsetzung (insbesondere in komplexe Computersysteme) gefährdet heute zunehmend die kognitive Autonomie des Menschen. Seinen besonderen Ausdruck findet dieses Denken in den Zielen der Künstlichen Intelligenz, denen die Metapher des künstlichen Menschen zugrunde liegt. Um die Beschränktheit mechanistischen Denkens deutlich werden zu lassen, wird die Geschichte des Begriffs von der griechischen Antike bis heute in ihren wichtigsten Stationen dargelegt. Das macht insbesondere den inhaltlichen Verlust sichtbar, den einschränkende Formalisierungen des Begriffsdenkens mit sich bringen. Es wird dafür plädiert, die enge Verbindung von Inhaltlichem und Formalem im Begriffsdenken zu reaktivieren; hierzu wird dem machanistischen Weltbild entgegengestellt das Weltbild der menschlichen Kommunikationsgemeinschaft, für das kommunikatives Denken und Handeln konstitutiv ist

    Abstract
    Katalogisierung über den Rechner bedeutet immer auch, einen OPAC aufzubauen, der es erlaubt, nach unterschiedlichen Merkmalen - formal und sachlich - und mit deren Kombination zu recherchieren. Die Freiwortrecherche wird von den Benutzern gern verwendet, obwohl dabei die Recall Ration (Vollständigkeit) nicht ausgeschöpft wird. Die Nutzung von Schlagwörtern sollte deren Standardisierung in einer Normdatei voraussetzen, um den Subjektivismus der Katalogisierer auszuschalten. Schlagwortketten sind prinzipiell für einen OPAC überflüssig. Bei Verwendung einer hierarchischen, d.h. systematischen Klassifikation sollte deren Notation systemkohärent, flexibel und synthetisch (Facetten bzw. Schlüssel) sein. Mit Hilfe von Registern sind Schlagwörter und Systemnotationen vice versa zu verknüpfen. Wenn Sachkatalogisierung im Verbund erfolgt, bilden Terminologiekontrolle und Einheitsklassifikation als Grobsysteme wichtige Desiderate

    Abstract
    Describes the work carried out on the TREC-2 project following the results of the TREC-1 project. Experiments were conducted on the OKAPI experimental text information retrieval system which investigated a number of alternative probabilistic term weighting functions in place of the 'standard' Robertson Sparck Jones weighting functions used in TREC-1

    Abstract
    Dieses Papier beschreibt, wie ein EG-finanziertes Projekt, unter Einbeziehung von 7 Nationalbibliotheken, die Entwicklung gemeinsamer Problemansätze bei CD-ROM Veröffentlichungen gefördert hat. Das Projekt als ganzes wird beschrieben und auf die Hauptergebnisse hingewiesen, einschließlich der Formulierung einer allgemeinen RetrievalSchnittstelle und der Entwicklung eines UNIMARC-Pilotprojektes auf CD-ROM unter Einbeziehung von 4 Nationalbibliographien. Das Papier beschreibt weiterhin in detaillierter Form die Hauptaspekte der Retrieval-Schnittstelle und die Methodologie für die Entwicklung einer CD-ROM von 4 unterschiedlichen bibliographischen Daten mit jeweils verschiedenen Formaten und Zeichensätzen

    Abstract
    This paper describes the Book House system which is designed to support children's information retrieval in libraries as part of their education. It is a shareware program available on CD-ROM and discs, and comprises functionality for database searching as well as for the classification and storage of book information in the database. The system concept is based on an understanding of children's domain structures and their capabilities for categorization of information needs in connection with their activities in public libraries, in school libraries or in schools. These structures are visualized in the interface by using metaphors and multimedia technology. Through the use of text, images and animation, the Book House supports children - even at a very early age - to learn by doing in an enjoyable way which plays on their previous experiences with computer games. Both words and pictures can be used for searching; this makes the system suitable for all age groups. Even children who have not yet learned to read properly can by selecting pictures search for and find books they would like to have read aloud. Thus at the very beginning of their school period, they can learn to search for books on their own. For the library community itself, such a system will provide an extended service which will increase the number of children's own searches and also improve the relevance, quality and utilization of the collections in the libraries. A market research on the need for an annual indexing service for books in the Book House format is in preparation by the Danish Library Center

    Abstract
    An exploratory research study on OPACs was done within the framework of the French PARINFO program by four different teams: ENSSIB-CERSI, City Univ. of London, Médiathèque of the Cité des Sciences et de l'industrie and a firm GSI-ERLI. During the month of June 1992, 650 individual searches on four terminals were collected. The sessions were automatically recorded, accompanied by two online questionnaires, a pre-search and a post-search questionnaire. Some questions were asked orally by an interviewer and the answers noted. The article analyses the researches perceived by user as difficult or impossible. Some examples of the difficulties are given
