Theoretical research has spent some years facing the problem of how to represent and provide semantics to updates of logic programs. This problem is relevant for addressing highly ...
Abstract. In this short paper we describe the DFL hybrid knowledge base, that integrates descriptions with expressive object-oriented rules. The knowledge base manages a database o...
This tutorial paper discusses a particular style of operational semantics that enables one to give a ‘syntax-directed’ inductive definition of termination which is very useful...
Bialgebraic semantics, invented a decade ago by Turi and Plotkin, is an approach to formal reasoning about well-behaved structural operational specifications. An extension of alg...
The semantics of constraint logic programming languages with coroutining facilities (\freeze," suspension, residuation, etc.) cannot be fully declarative; thus, an operationa...
