摘要:

本文提出了一种基于行为特征的网格实体信用度评估方法,旨在根据第三方所提供的相关于以往交互的信用度证据,来分析行为一致性、行为惯性等实体行为特征,指导信用 度的最终评定。实验结果表明,这种方法能够有效地提取实体行为特征,在此基础上给出的信用度评估结果合理性强、可靠性高。

Abstract:

We propose a behavior characteristics-based approach for reputation evaluation. The main idea is that: according to the reputation evidences from thethird parties, behavior characteristics such as behavior coherence, behavior inertia etc will be well abstracted, and reputation evaluation will be bet ter guided. Experimental results show that this approach can effectively catch the behavior characteristics of an entity, and the final evaluation resul t is reasonable and reliable.

Key words: (reputation, grid, approximation, behavior coherence factor, behavior inertia degree)
