A Knowledge-Based Approach to Ontologies Data Integration

This paper describes a proposal of multiple ontology data integration system for a question answering framework called AQUA. We propose an approach for mediating between a given query and a set of resources. This method is based on a Meta-ontology (which contains contents of each individual sources) and our similarity algorithm based on analysis of neighborhood of classes. We argue that AQUA can perform mappings between queries and an ontological space by using a mediator agent based on a Meta-ontology and our similarity algorithm.
