We describe Orel, a reasoning system for an ontology language which subsumes both the EL and the RL profile of the recently standardised web ontology language OWL 2. Orel performs ...
Abstract. A temporal logic is proposed as a tool for specifying properties of Klaim programs. Klaim is an experimental programming language that supports a programming paradigm whe...
The universal Horn theory of relational Kleene algebra with tests (RKAT) is of practical interest, particularly for program semantics. We develop an (infinitary) proof system, ba...
Logic programming with negation offers a compelling approach to abductive reasoning. This paper shows a simple view of abduction in this context for the completion semantics, unde...
In recent years researchers have developed a wide range of powerful automated reasoning systems. We have leveraged these systems to build Jahob, a program specification, analysis, ...
