【摘要】：反馈信息不能反映评价人的个人偏好,且其评价的重要程度随时间增加逐渐消减.为此,在充分考虑评价人的个人偏好基础上提出了一个基于信誉的信任管理框架.该框架主要包括基于决策树的信任计算模型和时间衰减计算模型.最终使得云服务的信誉值不再仅仅局限于反映云服务质量的一个客观数值,而是更能体现出不同云服务评价人的主观性.在该模型的基础上,进行了实验对比分析.实验分析结果表明,与现有的信誉评价模型相比,采用决策树和时间衰减模型信誉评价更为精确.
[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.
