【摘要】：反饋信息不能反映評價人的個人偏好,且其評價的重要程度隨時間增加逐漸消減.為此,在充分考慮評價人的個人偏好基礎上提出了一個基于信譽的信任管理框架.該框架主要包括基于決策樹的信任計算模型和時間衰減計算模型.最終使得云服務的信譽值不再僅僅局限于反映云服務質量的一個客觀數(shù)值,而是更能體現(xiàn)出不同云服務評價人的主觀性.在該模型的基礎上,進行了實驗對比分析.實驗分析結果表明,與現(xiàn)有的信譽評價模型相比,采用決策樹和時間衰減模型信譽評價更為精確.
[Abstract]:Feedback information can not reflect the personal preference of evaluators, and the importance of evaluation gradually decreases with time. Therefore, a trust management framework based on reputation is proposed on the basis of considering the personal preferences of evaluators. The framework mainly includes trust computing model based on decision tree and time attenuation calculation model. Finally, the reputation of cloud services is not limited to an objective value that reflects the quality of cloud services, but also reflects the subjectivity of different cloud service evaluators. On the basis of the model, the experiments are compared and analyzed. The experimental results show that the decision tree and time attenuation model are more accurate than the existing reputation evaluation model.
