摘要: 为了提高信任评价的准确性和主观逻辑的适用性,提出了基于多项式主观逻辑的扩展信任传播模型,该模型由信任融合和信任传递2部分组成。基于信誉的多项式观点的融合方法考虑信誉与观察环境对融合操作的影响,提高了信任评价的准确性,更符合人的直觉评判;信任传递把多项式观点的传递理解为传递过程是二项逻辑观点,而传递信息是多项式观点,给出了多项式观点的信任传递公式,并对相关定理进行了证明。最后,通过实例分析验证了模型的准确性和适应性。

Abstract: In order to improve the accurateness of trust evaluation and the applicability of subjective logic, a multinomial subjective logic based extended trust propagation model (MSL-ETPM) was presented, which is composed of trust fusion and trust transitivity. Making the fused opinion more accurate and more in line with the intuitive judgment of human, reputation-based fusion operator of multinomial opinions takes effects of the reputation value and observation circumstance into consideration. Trust transitivity interprets multinomial opinion transitivity as meaning that transitivity process is binomial logical opinion and transitivity information is multinomial opinion, giving trust transitivity formula of multinomial opinion and proving related theorem. Finally, the accuracy and adaptability of the model are put to the proof by example analysis.
