统一声誉量化方法的研究

ON UNITED REPUTATION METRIC

针对当前声誉模型中各种量化方法的多样性和异构性问题,提出基于主观逻辑的统一声誉量化方法URMetric,用于解决不同量化方法约束下声誉信息的孤立问题。并以目前一些声誉模型为例,说明如何通过映射函数将其中的声誉投影到URMetric上,以屏蔽各种不同量化方法之间的差异,为使用者提供了统一声誉量化方法。

Subjective logic-based untied reputation metric （URMetric） is proposed in this paper according to the multiplicity and heteroge- neity characteristics of various reputation metrics in current reputation models, to resolve isolation problem of reputation information under dif- ferent metrics＇ restriction. Some existing reputation models are taken as examples to illustrate the way to map their reputation values onto UR- Metric by mapping functions for shielding differences among various metrics, by which a united reputation metric is provided for users.
