Conflict Handling in Time-Dependent Subjective Networks

With this work, we contribute novel operators and perspectives to the field of subjective logic. We propose a novel multi-source trust revision approach enabling multi-source fusion, which considers majority tendencies to mitigate occurring conflicts. For this, the degree of conflict is extended for a multi-source use, which allows our definition of so-called conflict shares. Subsequently, combining our and existing trust revision methods, we propose a generalized trust revision approach. Extending trust revision to subjective networks describing time-dependent processes, we propose the use of sub subjective networks and further the transition to recursive subjective networks. Finally, our trust revision approach and the sub subjective network proposal are evaluated and demonstrated based on experiments, which show conflict handling favoring majorities and an efficient evaluation of time-dependent decision processes.
