Abstract
In this study, the effects of query structure and various setups of
translation dictionaries on the performance of cross-language information
retrieval (CLIR) were tested. The document collection was a subset of the
TREC collection, and as test requests the study used TREC's health related
topics. The test system was the INQUERY retrieval system. The performance of
translated Finnish queries against English documents was compared to the
performance of original English queries against English documents. Four
natural language query types and three query translation methods, using a
general dictionary and a domain specific (= medical) dictionary, were
studied. There was only a slight difference in performance between the
original English queries and the best cross-language queries, i.e.,
structured queries with medical dictionary and general dictionary
translation. The structuring of queries was done on the basis of the output
of dictionaries.
