The Logic of Trust

摘要: This thesis addresses two problems of trust: 1. Knowledge on Trust: If we are provided with information by a variety individuals, whom trust to different degrees, what is the best overall theory can form from given? 2. Social one does not have direct experience an individual, how establish initial degree through offices society? It first problem developing formal, mathematical and computational, model Bonjour’s Coherence Theory Knowledge, second adapting abstract argumentation reason about networks relationships distrust between individuals. In latter it develops notion generalised systems, giving their semantics via Galois Connections induced binary relations, provides general scheme evaluation these systems based propositional finding. Throughout, some effort made set work in context both theories day-to-day situations that encounters everyday life.
