- Abstract
- Examines the effectiveness of automated indexing and presents the results of a study of information retrieval from a segment (40.000 items) of the ULB Düsseldorf database. The segment was selected randomly and all the documents included were indexed automatically. The search topics included 50 subject areas ranging from economic growth to alternative energy sources. While there were 876 relevant documents in the database segment for each of the 50 search topics, the recall ranged from 1 to 244 references, with the average being 17.52 documents per topic. Therefore it seems that, in the immediate future, automatic indexing should be used in combination with intellectual indexing

- Abstract
- In diesem Aufsatz beschreiben wir ein System zur Analyse von Kurzartikeln. Das System arbeitet halbautomatisch. Das heißt, zunächst wird der Artikel vom System analysiert und dann dem benutzer zur Nachberarbeitung vorgelegt. Die so gewonnene Information wird in einem Datenbankeintrag abgelegt. Über die Datenbank - in dBase IV implementiert - sind dann Abfragen und Zugriffe auf die Originaltexte effizient möglich. Der Kern dieses Aufsatzes betrifft die halbautomatische Analyse. Wir beschreiben unser Verfahren für parametrisiertes Pattern Matching sowie linguistische Heuristiken zur Ermittlung von Nominalphrasen und Präpositionalphrasen. Das System wurde für den praktischen Einsatz im Bonner Büro des 'Forums InformatikerInnen Für Frieden und gesellschaftliche Verantwortung e.V. (FIFF)' entwickelt

- Abstract
- The test ran between Nov 95-Aug 96 in Cologne Fachhochschule fur Bibliothekswesen (College of Librarianship).The test basis was a database of 190,000 book titles published between 1990-95. MILOS II mechanized indexing methods proved helpful in avoiding or reducing numbers of unsatisfied/no result retrieval searches. Retrieval from mechanised indexing is 3 times more successful than from title keyword data. MILOS II also used a standardized semantic vocabulary. Mechanised indexing demands high quality software and output data
