(English Abstract)
The context-aware recommender system is a recommendation method considering the user's context in the existing method of the recommendation through the evaluation score of the users or the purchase history. As the Internet of Things become widely spread recently, the context-aware recommender system attracts the attention. However, the recommender system has a problem that is difficult to recommend to user with low volume of data. In addition, the sparse data problem of the recommendation method that reflects the context data is more serious than the existing recommendation method. Therefore, a recommendation method that can solve this problem is necessary. In this paper, we measure similarity by reflecting the number of items that are evaluated in common and apply context-aware collaborative filtering. As a result of the experiment, the proposed method is improved the recommendation performance compared with the existing similarity measurement and the proposed method is effective in the sparse data.
