    Abstract
    Das Passagen-Retrieval erlaubt explorierendes Navigieren in Volltextdatenbanken, aber auch in textorientierten Hypertextbasen. Es wird experimentell an fünf, im Information Retrieval geläufigen Assoziationskoeffizienten überprüft, inwieweit mit ihnen Textpassagen, gewonnen aus der Konversion von Absätzen aus einer Buchvorlage (Hypertextbuch von R. Kuhlen, 1991b), automatisch verknüpft werden können. Voraussetzung für die Anwendung der Maße ist eine Volltextinvertierung mit linguistisch abgesicherter Stammformenreduktion. Die Ergebnisse, gewonnen aus der Bewertung der Verknüpfungsangebote entsprechend den Berechnungen nach den fünf Koeffizienten und aus dem Vergleich mit einer intellektuellen Verknüpfungsvorgabe, zeigen eine deutliche Präferenz zugunsten des Asymmetrie-Maßes, das vielleicht noch durch eine Kombination mit dem Cosinus-Maß verbessert werden könnte. Die automatisch erstellten Verknüpfungsangebote sind sowohl im Autoren-Modus zur Unterstützung des Aufbaus von Hypertextbasen sinnvoll als auch im Lese-Modus als Möglichkeit des assoziativen Navigierens in großen Hypertextbasen verwendbar.

    Abstract
    The effectiveness ot two information retrieval tools, namely, thesaurus and natural language, in an information retrieval system has been studies. A database SOILSC was created using a HP3000/58 series minicomputer and MINISIS software. Records of articles totalling 17.918 published in various journals, received in the Central Water and Power Research Station (CWPRS) library (Pune, India) since 1988, have been stored. The information needs of a soil mechanics group have been formulated using thesaurus and natural language into 81 search strategies. In consultation with the user, relevance of the retrieved documents was assessed and, recall (R) and precision (P) values were calculated. Since both thesaurus and natural language have shown identical performance in information retrieval, a combination of these two have been suggested for making searches and providing relevant information

    Abstract
    The traditional measures of online searching proficiency (recall and precision) are less appropriate when applied to the searching of full text databases. The pilot study investigated and evaluated 5 measures of overall success in searching a full text data bank. Data was drawn from INQUIRER searches conducted by medical students at North Carolina Univ. at Chapel Hill. INQUIRER ia an online database of facts and concepts in microbiology. The 5 measures were: success/failure; precision; search term overlap; number of search cycles; and time per search. Concludes that the last 4 measures look promising for the evaluation of fact data bases such as ENQUIRER

    Abstract
    Homonymy is known to often cause false drops in free text searching in a full text database. The problem is quite common and difficult to avoid in Finnish, but nobody has examined it before. Reports on a study that examined the frequency of, and solutions to, the homonymy problem, based on searches made in a Finnish full text database containing about 55.000 newspaper articles. The results indicate that homonymy is not a very serious problem in full text searching, with only about 1 search result set out of 4 containing false drops caused by homonymy. Several other reasons for nonrelevance were much more common. However, in some set results there were a considerable number of homonymy errors, so the number seems to be very random. A study was also made into whether homonyms can be disambiguated by syntactic analysis. The result was that 75,2% of homonyms were disambiguated by this method. Verb homonyms were considerably easier to disambiguate than substantives. Although homonymy is not a very big problem it could perhaps easily be eliminated if there was a suitable syntactic analyzer in the IR system
