摘要: 为了解决当前社交网络中基于用户信任的Web服务推荐算法存在的覆盖率不足的问题,整合了当前有关直接信任、间接信任及群体信任度的研究思路,对相关的信任度计算方式进行了扩展研究。在此基础上,提出了一种新的混合信任度算法。 实验结果表明,在召回率、用户信任度和用户争议度等指标上该混合推荐算法优于现有算法ModelTrust,证明了该算法具有覆盖率较高的特点,能解决由单一信任度算法数据稀疏性造成推荐结果不佳的问题。

关键词: 社交网络,用户信任度,混合推荐算法,ModelTrust

Abstract: In order to solve the problem of insufficient coverage of current social networking Web service recommendation algorithm based on user’ trust,this paper incorporated the research ideas of direct trust,indirect trust and community trust, and did a lot of extended research on the calculation about trust.Based on these work,we proposed a new hybrid trust algorithm.We did a lot of experiments based on recall rate,user trust and user dispute.The experimental result shows that the hybrid algorithm has a good performance on coverage problem.Meanwhile,it can solve the problem that single trust algorithm’s sparse data lead to poor recommendation result.
