In nonmonotonic reasoning, a default conditional has most often been informally interpreted as a defeasible version of a classical conditional, usually the material conditional...
We report on a successful experiment of computeraided theorem discovery in the area of logic programming with answer set semantics. Specifically, with the help of computers, we d...
In this paper we give a robust logical and computational characterisation of peer-to-peer (p2p) database systems. We first define a precise model-theoretic semantics of a p2p sys...

We present a novel framework for the discovery and representation of general semantic relationships that hold between lexical items. We propose that each such relationship can be ...
We describe a new smart meeting room system called EasyMeeting that explores the use of FIPA agent technologies, Semantic Web ontologies, logic reasoning, and security and privacy...
