Outline of Final Research Achievements

For summarization of the newspaper editorials, it is important to grasp the author 's tone and to find issues and assertions. Therefore, we organized the tone types, and classified them into 4 types (speculation, assertion, hope, suggestion) and extracted issues and arguments. For opinion type classification, we used 4 features: words in sentences, positions of each sentence in the editorial, predicate in sentences, adverb appearing in sentences.
