A Global-to-Local Rewriting Querying Mechanism Using Semantic Mapping for XML Schema Integrationdocuments. In this paper, we discuss various strategies for rewriting the global query over the global schema into the sub-queries over local schemas. Their respective local schemas validate the sub-queries over the local XML documents. This requires the identification and use of mapping rules and r

A General Method for Pruning OWL Ontologiesge ontologies to create new ontologies in a semiautomatic (or assisted) way. When using a large ontology to create a more specific one, a key aspect is to delete, as much automatically as possible, the elements of the large ontology that are irrelevant for the specific domain. This activity is commo

Finding Compromises Between Local and Global Ontology Querying in Multiagent Systemsf agent-based applications, we propose a hybrid approach, in which part of the ontology is handled locally, using a “client component”, and the rest of the ontological knowledge is handled by an “ontology agent”, which is accessed by the other agents in the system through their client component. In

Aligning Ontologies and Evaluating Concept Similaritiessity of merging and aligning ontologies covering overlapping domains. However, a central issue in the merging process is the evaluation of the differences between two ontologies, viz. the establishment of a similarity measure between their concepts. Many algorithms and tools have been proposed for m

For the processing of EMMOs and the knowledge they contain, suitable querying facilities are required. In this paper, we present EMMA, an expressive query algebra that is ade
