Overview

This system analyzes the rhetorical structure of Japanese texts.

Configuration

Function

Texts such as editorials are written to show writer's opinion and thinking to readers. We call such opinion"Writer's Intention". We have developed a system which analyzes the rhetorical structure of Japanese texts from the view point of the Writer's Intention. This system makes use of five kinds of sentence information obtained from the results of morphological analysis: sentence type which is classified by its intention, topic information, demonstrative pronouns, conjunctive phrases and repeated words, and it analyzes a text structure using about 400 rules. These rules are based on analysis of Japanese context phenomena and are divided into 4 categories. The first category is for analysis of the relationship between a sentence and its adjacent one. The second category generates some groups of sentences using adjacent sentence relationships. The relationship between these groups will be analyzed in the third category. The fourth category develops text structure as the result of recognition of their elements.
