- Abstract
- Maschinelles Indexieren vereinheitlicht und vermehrt das Suchvokabular eines Bibliothekskatalogs durch verschiedene Methoden (u.a. Ermittlung der Grundform, Kompositazerlegung, Wortableitungen). Ein Retrievaltest mit einem für öffentliche Bibliotheken typischen Sachbuchbestand zeigt, dass dieses Verfahren die Ergebnisse von OPAC-Recherchen verbessert - trotz 'blumiger' Titelformulierungen. Im Vergleich zu herkömmlichen Erschließungsmethoden (Stich- und Schlagwörter) werden mehr relevante Titel gefunden, ohne gleichzeitig den 'Ballast' zu erhöhen. Das maschinelle Indexieren kann die Verschlagwortung jedoch nicht ersetzen, sondern nur ergänzen

- Abstract
- Proceedings of the llth TREC-conference held in Gaithersburg, Maryland (USA), November 19-22, 2002. Aim of the conference was discussion an retrieval and related information-seeking tasks for large test collection. 93 research groups used different techniques, for information retrieval from the same large database. This procedure makes it possible to compare the results. The tasks are: Cross-language searching, filtering, interactive searching, searching for novelty, question answering, searching for video shots, and Web searching.

- Abstract
- Considers intersearcher and intrasearcher consistency in the selection of search terms. Based on an empirical study where 22 searchers from 4 different types of search environments analyzed altogether 12 search requests of 4 different types in 2 separate test situations between which 2 months elapsed. Statistically very significant differences in consistency were found according to the types of search environments and search requests. Consistency was also considered according to the extent of the scope of search concept. At level I search terms were compared character by character. At level II different search terms were accepted as the same search concept with a rather simple evaluation of linguistic expressions. At level III, in addition to level II, the hierarchical approach of the search request was also controlled. At level IV different search terms were accepted as the same search concept with a broad interpretation of the search concept. Both intersearcher and intrasearcher consistency grew most immediately after a rather simple evaluation of linguistic impressions
