| Abstract(in English) | In this paper, we propose a opinion extraction method using a notion of syntactic piece. Syntactic piece is a minimum unit of structure. It is easy to use like n-gram and it has a part of syntactic structure. In the task of opinion extraction, syntactic piece can be high accuracy classification. Because, it contain both object of evaluation and sentiment expression. Therefore, we do not need to make dictionary for each domain. First, we made syntactic piece dictionary tagged positive or negative using training data, and classified sentence. Next, we generalized and extended dictionary to improve recall. As the result, the system performed 80% precision and 50% recall for multiple domains. |
