Abstract

This paper presents results for the Japanese/English cross-language informaiton retrieval task on teh NACSIS Test Collection. Two automatic dictionary-based query translation techniques were tried with four variants of the queries. The results indicate that longer queries outperform the required description only queries and that use of the first translation in the edict dictionary is comparable with the use of every translation. Japanese term segmentation posed no unusual problems, which contrasts sharply with results previously obtained for corss-language retrieval between Chinese and English.
