RDF(S) and OWL 2 currently support only static ontologies. In practice, however, the truth of statements often changes with time, and Semantic Web applications often need to repres...
In this paper we present an embedding of propositional production systems into µ-calculus, and first-order production systems into fixed-point logic, with the aim of using these...
This paper presents a logic-based bargaining solution based on Zhang and Zhang's framework. It is shown that if the demand sets of players are logically closed, the solution s...
We present one way of combining a logical framework and first-order logic. The logical framework is used as an interface to a first-order theorem prover. Its main purpose is to k...
Fuzzy formal logics were introduced in order to handle graded truth values instead of only ‘true’ and ‘false’. A wide range of such logics were introduced successfully, li...
