In this paper, we describe the process specification language ConGolog and show how it can be used to model business processes for requirements analysis. In ConGolog, the effects...
The aim of this paper is to build a formal model for similarity-based fuzzy unification in multi-adjoint logic programs. Specifically, a general framework of logic programming whi...
Abstract Narrowing extends rewriting with logic capabilities by allowing logic variables in terms and by replacing matching with unification. Narrowing has been widely used in diff...
