We consider an extension of bi-intuitionistic logic with the traditional modalities , , and from tense logic Kt. Proof theoretically, this extension is obtained simply by extendin...
This paper presents Abacus, a service-oriented programming language designed for the development of grid applications. Abacus considers that all the grid resources constitute a un...
We present the architecture and design details of a logic database system that extends functionality in a number of ways. The system supports indefinite (non-Horn) facts in extens...
Distributed Description Logics (DDLs) is a KR formalism that enables reasoning with multiple ontologies interconnected by directional semantic mapping (bridge rules). DDLs capture ...
This work addresses the issue of prioritized reasoning in the context of logic programming. The case of preference conditions involving atoms is considered and a refinement of th...
