This paper suggests the efficient indexing method based on a concept vector space that is capable of representing the semantic content of a document. The two informa- tion measure, namely the information quan- tity and the information ratio, are defined to represent the degree of the semantic im- portance within a document. The proposed method is expected to compensate the lim- itations of term frequency based methods by exploiting related lexical items. Further- more, with information ratio, this approach is independent of document length.
