Illegal Movie Detection by Using Comment Distribution Based on Temporal Correlation in NicoNico Douga
Hayato Shimizu, Kazuyuki Matsumoto, Minoru Yoshida, Kenji Kita (Tokushima Univ) DE2015-19
Abstract (in Japanese) (See Japanese page) 
(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.
