Database Access Through Ontologies With Semi-Automatic Semantic Mapping

A method for accessing databases through ontologies by using an IRIS (Information Representation, Inferencing and Sharing) architecture that includes nodes and links, the method comprising: representing a graph model of the ontologies, where the ontologies include concepts, properties, and relations; defining the graph model through high-level constraints; using a plurality of agents to formulate queries of the ontologies; allowing sections of the ontologies to be named and used as classes; creating an interface module based on definitions of the relations created by the plurality of agents for evaluating the high-level constraints; allowing the semi-automatic mapping of data into the ontologies; loading the data into the ontologies; allowing the plurality of agents to access the ontologies through the queries; and customizing the ontologies through views derived from the queries.
