摘要: 传统的推荐系统常用显式反馈进行个性化推荐,但显式反馈数据不易获取,质量不好且易引起用户反感,使推荐结果不能满足用户需求。隐式反馈数据更容易获取,可更好地为用户提供其感兴趣的内容。提出一种基于隐式反馈数据的个性化游戏推荐方法。该方法基于游戏时长、游戏次数等隐式反馈数据,构建针对游戏用户数据的隐式反馈推荐模型,通过隐语义推荐算法实现了游戏的个性化推荐。通过大量真实数据集的对比实验,表明该方法的精确率和召回率均优于其他方法。

Abstract: Traditional recommendation systems often use explicit feedback for personalized recommendations. But the explicit feedback data is not easy to obtain, and the quality is poor, and the recommendation results unable to meet the requitrment of the user. Implicit feedback data is easier to obtain and can provide users with the better content. A personalized game recommendation method based on implicit feedback data is proposed. The method builds an implicit feedback recommendation model for game user data based on implicit feedback data such as the game duration and game numbers. A personalized recommendation of the game is implemented through an implicit semantic recommendation algorithm. Through comparative experiments on a large number of real data sets, it is shown that the accuracy and recall of the proposed method are better than other methods.

Key words: recommended system, implicit feedback, LFM(Latent Factor Model), personalized recommendations
