| Abstract(in English) | In this paper, we evaluate the ablities of similar information retrieval (IR) methods : (1) a conventional information retrieval method ( the tf・idf method), and (2) an information retrieval method based on concept bases (knowledge of word meanings). The tf・idf method is very effective when the relevant documents include words in a query, but is ineffective when the relevant documents do not include words in a query. The IR method based on concept bases is effective when the relevant documents do not include words in a query. The combination of both methods is even more effective. |
