| 摘 要： | To describe the dynamic property of trust relationship, we propose a time-related trust model and extend Jφsang‘s subjective logic to fit for time-related trust model. The extension includes propositional conjunction, disjunction and negation for traditional logic and discounting and consensus operators that are evidential operators specially designed for the propagation and computation of trust relationships. With the extension of subjective logic for time-related trust, our time-related trust model is suitable to model the dynamic trust relationship in practice. Finally an example of reputation assessment is offered to demonstrate the usage of our trust model.

| Abstract: | To describe the dynamic property of trust relationship, we propose a time-related trust model and extend Jøsang's subjective logic to fit for time-related trust model. The extension includes propositional conjunction, disjunction and negation for traditional logic and discounting and consensus operators that are evidential operators specially designed for the propagation and computation of trust relationships. With the extension of subjective logic for time-related trust, our time-related trust model is suitable to model the dynamic trust relationship in practice. Finally an example of reputation assessment is offered to demonstrate the usage of our trust model. |
