一种基于社交网络舆论影响的推荐算法
A RECOMMENDATION ALGORITHM BASED ON THE INFLUENCE OF SOCIAL NETWORK OPINIONS
摘要
Abstract
The trust among friends is an important factor that affects users making decision in social network.Based on the topology of social network and trust degree of neighbor node, the recommendation system is constructed in this paper, and the recommendation algorithm is also presented.Then, some theoretical analysis and simulations have also been made out.The results show that the topology and trust degree in social network will have a great impact on user's anticipation for product during the process of social communication.The mount of recommender for single product in social network varies with time by following S-curve and the rank of recommended products obeys the power-law distribution with cut-off tail.This research not only analyzes the forming mechanism of user's anticipate, but also to some extent enhances the efficiency of recommendation by using the recommendation algorithm.关键词
