ABSTRACT
Recently, the customer reviews became many important and useful information about evaluation and/or needs of customers. Many research about sentiment analysis for the customer reviews were proposed aggressively. In this paper, we focus on evaluation sentence patterns and the words appearing in them to estimate sentiment values of texts, and compared with a Bag-of-Words-based SVM classification. We investigated how many feature words obtained by SVM are included in the words extracted from the sentences of evaluation sentence patterns, and roughly 75% are included, which suggests that to just focus on a limited number sentences of evaluation sentence patterns can produce a comparable result even in its early stage.
