抄録

This paper proposes a new method of relative words retrieval. In this method, firstly, the conceptual space, onto which a lot of words in the database are mapped by using the technique of the multidimensional quantification IV, is utilized for the preliminary retrieval of words. Next, the retrieved words are sorted to sophisticate the result based on conceptual intention, which can estimate relevance between words.<br>The features of this method are 1) it can retrieve apposite words without conisdering the dimensions of conceptual space, 2) it can retrieve appropriate words based on low-dimensional conceptual space that can be reconstructed easily. 3) it can reduce a size of memory which is used to store the eieenvectors is reduced
