| Abstract(in English) | This paper presents a novel approach mapping documents into a conceptual space. Many search systems are based on not concepts but simple words matching method. We have trouble in seeking an information by this method. Because it is hard for us to exchange concepts into words and words' usage differs by people. We define these difference words' noise. Our presented information retrieval method use not words but concepts generating words in documents. We remove the words' noise, infer the concepts from wrods and map documents in the concept space. The relation of documents is measured not words in documents but concepts. The measure based on the concepts approximates the esseptial similarity between documents' contents. Therefore the precision of documents classification improves, and users can search by their concepts. |
