Abstract :
In this paper, we present a new creation method of a semantic retrieval space for a specialized field of study, especially for the field of International Relations (IR), and new evaluation criteria for verifying practical effectiveness of the created space. This space creation method needs only a general dictionary and a lexicon of the technical terms for a specific field. Using the newly created space, we realized semantic associative search for documents which include various technical terms with general words, and also documents which include general words with technical terms. Furthermore, to verify practical effectiveness of the space creation method, that is, how much knowledge we can acquire from the created space newly, we present some evaluation criteria besides precision and recall rate.
