Abstract

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.
