- Abstract
- OSIRIS und ELIB sind von der Deutschen Forschungsgemeinschaft (DFG) und dem Niedersächsischen Ministerium für Wissenschaft und Kultur (MWK) geförderte Projekte an der Universität Osnabrück. Sie beschäftigen sich mit intuitiv-natürlichsprachlichen Retrievalsystemen und mit Fragen der Indexierung großer Volltexdatenbanken in dieser Technik. Die Entwicklungen haben dazu geführt, daß an sich aufwendige und komplexe Verfahren der syntaktisch-semantischen Analyse und Bewertung von textuellen Phrasen in relationale Datenbanken für Massendaten eingebettet werden konnten und nun im Produktionsbetrieb eingesetzt werden können

- Abstract
- Der Artikel stellt Ergebnisse einer Studie zur vergleichenden Bewertung von Verfahren der nachfrageorientierten Inhaltserschließung im Volltextarchiv der Stuttgarter Zeitung vor. Im ersten Teil der Arbeit wird empirisch untersucht, ob in der digitalen Pressedokumentation auf eine intellektuelle Indexierung von Artikeln verzichtet werden kann, wenn ausschließlich im Volltext recherchiert wird. Im zweiten Teil der Arbeit werden Möglichkeiten und Grenzen einer innovativen Inhaltserschließung von Volltexten in der Textdokumentation der Stuttgarter Zeitung mittels Digitaler Textdossiers diskutiert

- 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
- Reviews developments and improvements in techniques for searching the WWW that have been made access to full text databases a practical proposition (full text retrieval (FTR)). Reports results of interviews with 8 full text database vendors offering FTR via the WWW: Dataware (http://www.dataware.com); Excalibur (http://www.excalib.com); Fulcrum (http://www.fulcrum.com); Muscat (http://www.muscat.co.uk); Open Text (http://www.opentext.com); Personal Library Software (PLS) (http://www.pls.com); Verity (http://www.verity.com); and ZyLab (ZyIndex and ZyImage) (http://www.zylab.com). Compares the prices of the systems and lists the questions that publishers should ask before making a choice of systems for handling FTR on the Web

- Abstract
- At Rotterdam Ports Authority in the Netherlands the Habour information database includes a press cuttings service and various online databases. To enable research staff to have direct access to information the POINT (Point Information Net) was begun in 1993. Using Verity software POINT provides simultaneously full text searching on a range of databases. The software uses current Web indexing technqiues to overcome the problems of excessive recall and low precision. A key element is the system's ability to recognise word combinations

- Abstract
- Verity Search 97 software will index and search e-mail, attachments, folders and documents on local and network disk drives. The Internet may be searched via the same front end and changes to particular documents or pages may be monitored. Documents may be viewed in their native formats including ASCII, HTML, PDF and popular word processors, with highlighted search terms. Agents may be launched into the Internet to retrieve information according to a user-specified profile. The software can index about 700 MB an hour. Describes the search technology which includes fuzzy logic and natural language. The Web version of Personal Search 97 works with Netscape Navigator or Microsoft Internet Explorer, while the Exchange version will work regardless of any attachment to an Exchange server. Search 97 Personal improves online time and access time and allows searches to be refined offline
