| Abstract(in English) | We participated in the 7th Text REtrieval Conference (TREC-7) held in November, 1998. In this paper, we outline the ad hoc task, which is the main task of TREC-7, and 7 sub tasks. We also describe the results of the various participants on these tasks and discuss the forthcoming TREC-8. Furthermore, we describe our method for TREC-7, using query expansion based on both an existing thesaurus (WordNet) and thesauri acquired automatically from a corpus. |
