Nominal calculi have been shown very effective to formally model a variety of computational phenomena. The models of nominal calculi have often infinite states, thus making model ...
Abstract—A growing number of applications start using Semantic Web technologies. The base concept in this technology is the use of ontologies, allowing first-order logic reasoni...
Answering queries posed over knowledge bases is a central problem in knowledge representation and database theory. In databases, query containment is one of the important query op...
Ontologies are set to play a key role in the "Semantic Web", extending syntactic interoperability to semantic interoperability by providing a source of shared and precise...
With the advent of web services standards and a serviceoriented Grid architecture, it is foreseeable that competing as well as complimenting computational services will proliferat...
