| Abstract(in English) | This paper attempts to extract_specific document sets containing the same topic from masses of documents. The original documents are classified through a decision tree and the classification results are analyzed with the decision tree structure. Focusing on classification accuracy in each of decision tree leaves, the analysis yields several tens of specified nouns and pairs of nouns, of which existence identifies the class of each document. Then, topic identification ability of the nouns is ascertained using similarity and entropy of documents in each leaf. As a result, most of the nouns can specify document topics. The resulting topics are not sufficient for applying to new communication services. However, several parts of the decision tree can indicate efficient extraction of topic. |
