Deciding expressive description logics in the framework of resolution
We present a decision procedure for the description logic SHIQ based on the basic superposition calculus, and show that it runs in exponential time for unary coding of numbers. To...

Symbolic Negotiation in Linear Logic with Coalition Formation
In this paper we present a formalism for symbolic negotiation. We regard symbolic negotiation as cooperative problem solving (CPS), which is based on symbolic reasoning and is ext...

A Family of Defeasible Reasoning Logics and its Implementation
Abstract. Defeasible reasoning is a direction in nonmonotonic reasoning that is based on the use of rules that may be defeated by other rules. It is a simple, but often more effic...

Paraconsistent Resolution for Four-valued Description Logics
Abstract. In this paper, we propose an approach to translating any ALC ontology (possible inconsistent) into a logically consistent set of disjunctive datalog rules. We achieve thi...
