- Abstract
- Describes the comparative approach to system evaluation used in this research project which delegated the administartion of an online retrieval test to an experimental online catalogue to produce data for evaluating the effectiveness of a new subject access design. Describes the methods enlisted to sort out problem test administration, e.g. to identify out-of-scope queries, incomplete system administration, and suspect post-search questionnaire responses. Covers how w the researchers handled problem search administrations and what actions they would use to reduce or eliminate the occurrence of such administrations in future online retrieval tests that delegate control of retrieval tests to online systems

- Abstract
- Purpose - The aim of the current paper is to test whether query translation is beneficial in web retrieval. Design/methodology/approach - The language pairs were Finnish-Swedish, English-German and Finnish-French. A total of 12-18 participants were recruited for each language pair. Each participant performed four retrieval tasks. The author's aim was to compare the performance of the translated queries with that of the target language queries. Thus, the author asked participants to formulate a source language query and a target language query for each task. The source language queries were translated into the target language utilizing a dictionary-based system. In English-German, also machine translation was utilized. The author used Google as the search engine. Findings - The results differed depending on the language pair. The author concluded that the dictionary coverage had an effect on the results. On average, the results of query-translation were better than in the traditional laboratory tests. Originality/value - This research shows that query translation in web is beneficial especially for users with moderate and non-active language skills. This is valuable information for developers of cross-language information retrieval systems.

- Abstract
- Seit einigen Jahren hat sich in Europa eine Initiative zur Bewertung von Information Retrieval in mehrsprachigen Kontexten etabliert. Das Cross Language Evaluation forum (CLEF) wird von der EU gefördert und kooperiert mit Evaluierungsprojekten in den USA (TREC) und in Japan (NTCIR). Dieser Artikel stellt das CLEF in den Rahmen der anderen internationalen Initiativen. Neue Entwicklungen sowohl bei den Information Retrieval Systemen als auch bei den Evaluierungsmethoden werden aufgezeit. Die hohe Anzahl von Teilnehmern aus Forschungsinstitutionen und der Industrie beweist die steigende Bedeutung des sprachübergreifenden Retrievals
