Abstract
A conceptual fuzzy set (CFS) expresses the meaning of a word in the distribution of activations of other words. It was proposed attempting to express word ambiguity influenced by varying contexts. In English sentences a generation method has been proposed paying attention to word sequences just before the target word. First, we predict a next word of word sequences just before the target word by using the modified confabulation model and obtain a synonymy. Second, we generate a CFS taking weighted summation of the synonymies reflecting contextual information. But in Japanese sentences the meaning of a word is determined by modification structures rather than a word order and it is difficult to presume the meaning of a target word using a word sequence. In this study we propose a method to generate a CFS using a modification structure in Japanese sentences. As a result of experiments, we show that the proposed method is effective to generate a CFS reflecting contextual changes.
