Goal generation from beliefs based on trust and distrust

چکیده
We propose three alternative belief change operators to be used in a goal generation and adoption framework. The originality of these operators is that the trustworthiness of a source depends not only on the degree of trust but also on an independent degree of distrust. Explicitly taking distrust into account allows us to mark a clear difference between the distinct notions of negative trust and insufficient trust. More precisely, it is possible, unlike in approaches where only trust is accounted for, to “weigh” differently information from helpful, malicious, unknown, or neutral sources.

متن کاملGoal generation with relevant and trusted beliefs
A rational agent adopts (or changes) its goals when new information (beliefs) becomes available or its desires (e.g., tasks it is supposed to carry out) change. In conventional approaches to goal generation in which a goal is considered as a “particular” desire, a goal is adopted if and only if all conditions leading to its generation are satisfied. It is then supposed that all beliefs are equa...
