This paper reports the methods and procedures we took in the CLIR track of NTCIR3. In monolingual subtasks we mainly describe index representation and word segmentation method. We use hybrid model integrating MT approach and dictionary-based approach in bilingual and multilingual subtasks. The method for combining the monolingual retrieval results to produce the final rank list is explained in detail. Finally, we present an improved query translation method in CLIR in order to get better query translation quality.
