摘要:  

摘要: 信任信誉机制是电子商务中建立公平交易环境、促进交易量的重要基础。当前电子商务中信任计算普遍动态性不足,缺乏激励机制。本文提出一种新的信任计算模型,该模型中一方对另一方的信任包括两部分:一是从交易双方的直接交易历史经验中得到的直接信任;二是该交易方通过另一方的全局信誉获得的间接信任。该模型考虑时间因素对信任的影响,引入可信时间窗口的概念和对恶意交易的惩罚机制,由此带来的信任动态性可以有效促进双方公平交易的积极性。信任动态性会导致稳定性问题,本文研究如何平衡信任的动态性与稳定性。实验结果表明,该信任模型具有良好的动态性和稳定性,有助于建立公平而富有活力的电子商务交易环境。

Abstract:  

 Abstract:  Currently, most researches on trust model are focused on its computability and diversity, but ignore its dynamics and stability. This paper presents a new trust model for Ecommerce system focusing on its dynamics and stability. In this trust model, peer A’s trust in peer B consists of two parts: A’s direct trust in B and the reputationbased trust of B. A’s direct trust in B is computed according to A’s rating about their transactions. The reputationbased trust of B is computed according to all peers’ transaction rating to him. Considering influence of the time factor, a new concept named credible time window is defined and a punishment mechanism for failed transactions is designed, so the dynamics trust model can motivate a fair exchange effectively. The dynamics of the model can affect the stability, how to balance them in different situation is studied. The experimental results show that this model outperforms the existing trust models in dynamics, and it can make a balance between its dynamics and stability as required.
