Abstract (in Japanese) (See Japanese page) 
(in English) In blog activity, the changes of the way of thinking for the category are caught by time when users classify the entries which they described in a category. In this paper proposes the system which visualizes the user's classification criteria and shows the changes of those criteria by time, using the model of Learning Vector Quantization: which is the prototype-based supervised classification algorithm. In addition, by Singular Value Decomposition, the system processes the ambiguousness and similarity of the words.
