Mapping Ontologies - Tools, a Suite, and an Application

Before continuing, I want to devote a little space to fleshing out the subject of Mapping Ontologies, which I have alluded to in a couple of earlier posts. Mapping is a process in which we first try to find similarity between individual elements of two ontologies. We compare the elements on the basis of their names and attributes.

Note: Protégé (see my August 24 post below) is probably the most popular ontology editor available.

Using NeOn Toolkit

Note: The Watson plug-in to the NeOn Toolkit (see my September 27 post below) allows the user to select entities of the currently edited ontology and to automatically trigger queries to a remote ontology.

A proposed Web app that addresses a real-world situation with the help of ontology mapping, probabilities, and Jena - a Semantic Web framework for Java.

When incorporating data semantics into the searching process, the correctness of searching can depend directly on mapping results.
