Lotrec: Logical tableaux research engineering companion

www.irit.fr/recherches/LILaC/Lotrec/ Abstract. In this paper we describe a generic tableaux system for building models or counter-models and testing satisfiability of formulas in modal and description logics. This system is called LoTREC2.0. It is characterized by a high-level language for tableau rules and strategies. It aims at covering all Kripke-semantic based logics. It is implemented in Java and characterized by a user-friendly graphical interface. It can be used as a learning system for possible worlds semantics and tableaux based proof methods.
