| 摘 要： | 提出一种加权RFM与协同过滤相结合的集成推荐方法,对由"Web数据挖掘"隐式收集的客户评价数据进行协同过滤处理,应用加权RFM对相似用户聚类结果加以改进,从而更有效地发现推荐规则,提高推荐质量。同时应用产品分类树(PT)对产品进行预处理,以减少计算空间的复杂度。实验评价结果表明该方法无论在推荐精度还是推荐相关性上都更为有效。

| Abstract: | In this paper,an integrated recommender method which employs weighted RFM and CF method is presented.Firstly,CF is applied to customer ratings on products,which are collected implicitly by Web usage mining approach,then weighted RFM is applied to improve similar user clustering to find recommend rule effectively and generate better quality recommendations.Product Taxonomy(PT) is also used to preprocess products according to their categories and to reduce dimensions of computational space.Evaluation results show that the proposed method is more effective both in the accuracy and relevance of recommendations. |
