Abstract

Studies relevance relations in the context of propositional logical theories and subject matters or topics of interest, which are taken to be sets of atomic propositions. Introduces the class of regular belief models and a notion of prime implicates applicable to all forms of this type of belief. Introduces implicit belief, which has a classical possible world model. discusses definitions of relevance for regular belief using implicit belief as a running example. Focuses on connections between relevance under implicit belief and work in the literature and computational aspects. Discusses relevance under explicit belief, which is based on a 3 valued extension of possible world semantics
