中文摘要：

随着社会网络关系的不断复杂化,商品是否推荐成功,除了基于商品本身的特征外,还受社会网络关系的影响。很多用户更加信任来自朋友的推荐,而非机器通过单因素计算出来的推荐结果。因此,设计了一个融入社会网络关系的电子商务推荐系统。其中,构建了社会网络关系强度、兴趣偏好强度和商品流行性与声望强度3个关键因子,每个一级因子又由若干个二级因子构成。实验结果验证了社会网络关系会对其中成员的网购等网络行为产生影响,构建的基于社会网络的电子商务推荐策略的效果比其他单因素推荐策略好且稳定,具有很好的实际应用效果。

英文摘要：

With the development of the social network relation, whether the recommendation is successful, is not only depending on the characteristics of goods, but also influenced by social network relationship. Many users more trust from their friends＇recommendation, rather than the machine recommended by single factor calculated results. Therefore, an E-commerce recommending system based on social network collaborative filtering was proposed. In the system, the crucial factors of social network relation intensity, interest preference intensity and production popularity with reputation intensity were set. And each first-level factor was composed of some second-level factors. Experimental results verify that social network relationships will affect users shopping behaviors and so on. In addition, the recommendation method based on social network is superior to other approaches and has better application effect.
