一种基于推荐的Web服务信任模型

Trust Model of Web Services Based on Recommendation

借鉴信任管理概念和Beth信任模型,提出了一种基于推荐的新型自适应Web服务信任模型,给出了相应的信任度和信任度合成的方法,并针对恶意推荐采取惩罚机制。实验证明,该模型可以使得实体的信任度能根据服务经验自适应地变动,并能根据惩罚机制对欺骗的实体进行惩罚,从而在一定程度上减少访问到恶意实体的次数。

Based on to trust management concept and Beth trust model, this paper proposes a new adaptive recommend trust model of Web services, and the corresponding algorithms of its trustworthiness and combine trust, and the punish mechanism for vicious recommendation is provided. The results of simulated experiment show that the model enables the trustworthiness of entities to self adapt with the increase of Web services experience, and punish deceitful entities according to punish mechanism, to some extent, can decrease the number of accessing vicious entities.
