| Abstract(in English) | Recently, the video sharing site such as NicoNico Douga or YouTube are used for various uses by individuals and corporations. The authors of the video often make a profit by uploading videos. However, because the video rating method is based on the frequency of looking and listening or the number of posted comments, the rating of the video can be intentionally increased by the author. We proposed the illegal video detection method by focusing on the correlation of temporal comment distribution rather than the frequency of looking and listening. The success detection rate of the proposed methodwas compared with the baseline binary classification method by using machine learning based on the word features. |
