Abstract:

      As we all know, the purpose of a recommendation system is to provide users with personalized recommendations to improve the user’s reliance on the platform and satisfaction. However, the sparsity of the interaction data between users and products often leads to unsatisfactory recommendation results. In recent years, the recommendation model based on users’ comments has become a research topic in the field of recommendation. However, we also face the problem of the insufficient information towards the users’ comments text, including the phenomenon of insufficient number of comments and too brief comments. This report will introduce a method to improve the accuracy of product rating prediction by mining peer review data. This work can be done to improve the quality of recommendations by extracting features for current user and product pairs from helpful comments written by like-minded users who have similar interests to the current users.
