Abstract(in Japanese) (See Japanese page)
Abstract(in English) In order to analyze the discourse structure, it is necessary to derive the themes and track their connections. The method to derive the theme has been so ambiguos that no analysis could be performed using the theme. This paper firstly classifies the sentences into verb, adjective, and noun ones. Based on the restriction for their types, the algorithm to derive themes and focuses is obtained. The application of this algorithm to the practical text makes 83.9% successful rate. Secondly, the context in discourse is analyzed using the derived themes. The analysis is made by labelling the themes, and then deriving the transfer fo the topic types using the label. In the result, it is possible to analyze the transfer of the topics.
