In these days, the internet, chat and weblog have lowered our barriers to the posting comments and information on Web sites. Because they are easy to use, their users are increasing yearly. These comments and information involve user's opinions, impressions and evaluations of certain objects, so there is a need for extraction of valuable information from these comments posted by many people. But it is harder to analyze those free descriptions quantitatively than to analyze numerical data. In this paper, we propose an estimation approach by using Rakuten GORA reviews. It estimates 5-point scale from free descriptions. First, we extract nouns related to each question and words of modification relation. Second, we analyze relationship between distributions of 5-point scales and those extracted words and find an estimation approach. Then we apply that method to the other reviews and compare estimation result to real data. |
