一种基于社会网络的信任模型

Modeling of Trust with Social Network

社会网络是通过朋友关系、工作关系和信息交换等一组社会机制,将人、组织和其他社会团结联系在一起形成的网络,Web就是一种社会网络。在社会网络中要求有一种自然的机制对网络的真实性进行判断和评价,信任模型就是比较好的一种机制。基于社会网络,本文构建了一种网络信任模型,用来估算信任者和被信任者之间的信任等级,能够用于语义网的信任管理系统和社会网络的信任评价中。实验结果表明,该模型具有很好的效率和效果。

A social network is a set of people,organization or other social entity connected by a set of social relationships,such as friendship,co-working or information exchange.The Web is an example of a social network.Trust is viewed as a measurable belief that utilizes personal experiences,experiences of other or possibly combined experiences,to make trustworthy decisions about an entity.In this paper,a new method for modeling and evaluation trust is proposed.The proposed method may be employed as trust evaluation in human interaction in social networks.Experimental result illustrates the efficiency and effectiveness of the proposed method.
