Transaction Logic is an extension of classical logic that gracefully integrates both declarative and procedural knowledge and has proved itself as a powerful formalism for many ad...
We introduce an alternative conceptual basis for default reasoning in Reiter's default logic. In fact, most formal or computational treatments of default logic suffer from th...
Abstract. In this paper, we extend Simple Conceptual Graphs with Reiter’s default rules. The motivation for this extension came from the type of reasonings involved in an agronom...
Abstract. In this paper, we present a logic R for rule bases by introducing a set of rule connectives. We define both the models and extensions of a rule base. The semantics of ex...
In nonmonotonic reasoning, a default conditional has most often been informally interpreted as a defeasible version of a classical conditional, usually the material conditional...
