In this paper, we propose a family of operators for merging stratified knowledge bases under integrity constraints. The operators are defined in a model-theoretic way. Our merging...
We recently proposed action formalisms based on description logics (DLs) as decidable fragments of well-established action theories such as the Situation Calculus and the Fluent C...

A powerful approach to finding errors in computer software is to translate a given program into a verification condition, a logical formula that is valid if and only if the program...
Ontologies represent the next important phase of the World Wide Web, creating a semantic web which links together disparate pieces of information and knowledge. Creating ontologie...
This paper describes the derivation of a program for the propagation of information over a network, with acknowledgement (feedback) when the computation is complete. The derivatio...
