Automatische Indexierung Für Online-Kataloge : Ergebnisse Eines Retrievaltests. Lepsky, K., Siepmann, J., & Zimmermann, A. Zeitschrift für Bibliothekswesen und Bibliographie, 43:47-56, 1996.
abstract   bibtex   
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.
