Incremental Collaborative Filtering Recommendation Method for Personalized Websites
摘要
Abstract
In order to solve the problems that user’s retrieval intention is rarely considered in the personalized websites and the search result is not good, this paper proposes an Incremental Collaborative Filtering Recommendation method (ICFR). The ICFR model improves the collaborative filtering recommendation algorithm, which is one of the most popular recommendation algorithms, and applies it to the personalized websites. Firstly, the browsing behavior information of users is extracted by analyzing web logs and normalized into rating value. Secondly, the similarity value between users is obtained by using the improved similarity calculation method, and the nearest neighbor set which can reflect the user’s intention is selected. Thirdly, the results predicted by the nearest neighbor set are sorted and returned to the user as the rec-ommended list. Finally, historical user preference data are updated effectively in real time by the incremental updating algorithm. The experimental results indicate that the incremental collaborative filtering recommendation model is suitable for personalized websites and this method can make the retrieval results reflect the user intention.关键词
