The purpose of the recommendation system is to provide users with personalized recommendations to increase user dependence and satisfaction with the platform. However, the sparseness of user-commodity interaction behavior data often leads to unsatisfactory recommendations. In recent years, the recommendation model based on user comments has become a research hotspot in the field of recommendation. However, the user's comment text itself will also face the problem of insufficient information, such as insufficient comments and short comments. This report will introduce a work to improve the accuracy of "product score" prediction by mining the user's comment data. For a given user-item pair, this work can extract features from the auxiliary comments written by other users with similar interests of the current user, thus to better improve the quality of the recommendation.
