| Abstract(in English) | Using users' comments from a movie information site, movies were classified based on Naive Bayes classification. Evaluation was done bycomparing the results to existing genre classification. For the objective evaluation of the classification precision, we employed the average precision. We attested an average precision of about 0.7 over 10 experiments. When we look into the movie classification from this experiment detailedly, we notice that even in the case in which the existing genre classification and machine classification differ, the machine classification data holds valuable information. As future research, we want to investigate how to incorporate this data into a movie search system. As preparatory data in order to achieve this goal, we will report the results of our analysis of cases in which the Naive Bayes classification and existing classification differ. |
