Abstract:
In this study, we investigate that the evaluations of answers in a Q&A site are affected by whether the first polar words are negative words. We first investigate answers where the first polar words were negative words. The result shows that the evaluations of answers in a Q&A site were less affected by whether the first polar words were negative words. Furthermore, we investigate users in a Q&A site who submitted many answers where the first polar words were negative word. The result show that answers submitted to a Q&A site were evaluated based on whether their explanations were detailed and informative, rather than whether the first polar words were negative words. In this study, we use the data of Yahoo! chiebukuro, a widely-used Japanese Q&A site, for observation and examination. We also use the opinion extraction tool and model data, which were developed by Knowledge Clustered Group in National Institute of Information and Communications Technology (NICT).
