| Abstract(in English) | Recently, recommendation algorithm and services has been studied, which provide appropriate contents or items from a large amount of available contents or services based on personal and contents profiles. So far, content-based filtering and collaborative filtering have widely been used as a recommendation algorithm. They, however, have problems such as unsuitable formalization of human perception and preferences based on content analysis, and extreme sparsity of available data as users typically rate only very few contents. We are now studying a recommendation system based on Bayesian network to solve these issues. In this paper, we first describe requirements for recommendation, then describe model definition policy and an example model based on the results of the questionnaire about movie preference taken from 1600 users. |
