摘要/Abstract

摘要：

依据信任的认知特征,分析了信任2个维度对角色信任的不同贡献,给出了服务信任和推荐信任的定义和量化公式.在信任网络中,分析了信任预测的3种情况及其社会网络特征,以代理的服务信誉为核心,设计了具有直接信任和传递信任的不同信任预测方案.设计方案中综合考虑了交互次数、交互时间、角色信誉、服务信任和推荐信任对信任预测的影响.最后的实验验证了角色信任的量化差异以及信任预测方法的有效性.

关键词: 信任预测, 角色信任, 信任网络, 信任传递

Abstract:

Trust network is a social network and is constructed by trust relationships between agents. Different contributions devoted by two dimensions of trust are analyzed, and definitions of service trust and recommendation trust are given. The social characteristics of the trust network is studied and a trust prediction method based on agent’s role-based trust and reputation is proposed. The influences of interactions number, time, reputation, service trust and recommendation trust are comprehensively considered which concord with the cognitive semantics of trust computing and propagation in trust network. The experiment verifies the differences of the role-based trust values and the effectiveness of trust prediction.

Key words: trust prediction, role-based trust, trust network, trust propagation
