| Abstract(in English) | In order to evaluate a similarity between two texts, a similar text retrieval system compares words that extract from texts. However, the words in the texts change as a time transition. Therefore, this paper explains how to decide time stability of words automatically by using a decision tree algorithm (C4.5). In this paper, we define five attribute from the distribution map of word frequency. In evaluation, we used the words that extracted from reports about professional baseball of Mainichi Shinbun Newspaper (1994-1998), and it is confirmed that the defined attributes are effective for deciding time stability of words automatically. |
