A construction method of a retrieval space by an evaluation of word distributions in documents

Abstract

This paper presents a new construction method of a retrieval space by an evaluation of word distributions in documents. In order to realize a semantic associative search, it is necessary to construct a retrieval space which enables measurement of relations between each word. A creation method of retrieval space has been proposed that creates a data matrix by using a dictionary or a term dictionary. However, it is difficult to create a retrieval space without a dictionary or a term dictionary. This method can construct a retrieval space which enables measurement of relations between each word by an evaluation of word distributions in documents. This paper shows some experimental results which applied the mathematical model of meaning to the retrieval space constructed by this method.
