Recently there has been a growing interest of research in tabling in the logic programming community because of its usefulness in a variety of application domains including progra...
The problem of representing and reasoning about two notions of time that are relevant in the context of knowledge bases is addressed. These are called historical time and belief t...
Abstract. This paper proposes a tool to support reasoning about (partial) correctness of constraint logic programs. The tool infers a speci cation that approximates the semantics o...
Concept analysis transforms any relation between ‘lobjects” and “attributes” into a complete lattice. This concept lattice can be studied by algebraic means and offers rem...
Undefined terms involving the application of partial functions and operators are common in program specifications and in discharging proof obligations that arise in design. One wa...
