    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

    Abstract
    Dieser Beitrag baut auf dem Bericht über das methodische Konzept, über die Durchführung und die Ergebnisse der PADOK-II-Retrievaltests auf (Krause/Wormser-Hacker). Hier werden die Ergebnisse von Zusatztests zum Einfluß des Umfangs der zugrundeliegenden Dokumente (Volltext vs. Titel+Abstract) beschrieben, die eine deutliche Beeinträchtigung der Recall-Werte bei reduziertem Dokumentenumfang zeigen. Zur interpretativen Analyse der Retrievalprotokolle werden vor allem die methodische Einbindung, Ansatzpunkte der Analyse und erste Ergebnisse vorgestelt.

    Abstract
    Im Rahmen von MILOS II wurde das erste MILOS-Projekt zur automatischen Indexierung von Titeldaten um eine semantischer Komponente erweitert, indem Thesaurusrelationen der Schlagwortnormdatei eingebunden wurden. Der abschließend zur Evaluierung durchgeführte Retrievaltest und seine Ergebnisse stehen im Mittelpunkt dieses Texts. Zusätzlich wird ein Überblick über bereits durchgeführte Retrievaltests (vorwiegend des anglo-amerikanischen Raums) gegeben und es wird erläutert, welche grundlegenden Fragestellungen bei der praktischen Durchführung eines Retrievaltests zu beachten sind

    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

    Abstract
    Proceedings of the 5th TREC-confrerence held in Gaithersburgh, Maryland, Nov 20-22, 1996. Aim of the conference was discussion on retrieval techniques for large test collections. Different research groups used different techniques, such as automated thesauri, term weighting, natural language techniques, relevance feedback and advanced pattern matching, for information retrieval from the same large database. This procedure makes it possible to compare the results. The proceedings include papers, tables of the system results, and brief system descriptions including timing and storage information

    Abstract
    The evaluation of information retrieval systems is an important yet difficult operation. This paper describes an exploratory evaluation study that takes an interpretive approach to evaluation. The longitudinal study examines evaluation through the information-seeking behaviour of 22 case studies of 'real' users. The eclectic approach to data collection produced behavioral data that is compared with relevance judgements and satisfaction ratings. The study demonstrates considerable variations among the cases, among different evaluation measures within the same case, and among the same measures at different stages within a single case. It is argued that those involved in evaluation should be aware of the difficulties, and base any evaluation on a good understanding of the cases in question
