| Research Abstract |
A large number of contents are being uploaded as online novels. I proposed two ranking methods. One is based on viewer's sentimental comments, and the other is based on the users' favorite lists (bookmarks). Relation between users and favorites can be represented as a bipartite graph. In several genres, the later one can predict future popular contents.
I studied semantic hierarchization of tags, which is given by many users. The hierarchy is based on frequency and co-occurrence of tags, and a hierarchy is represented as a direct acyclic graph. However, the automatic generation of tag hierarchy is not enough for automatic categorization. More careful study is need for automatic categorization.
