OntoMap is a knowledge a representation formalism, a reasoner, and a web portal for upper-level ontologies and lexical semantics. The KR language is more complex than RDF(S) and pretty similar to OWL Core. The portal provides access to the most popular upper-level and lexical resources, together with hand-crafted mappings between them. It includes number of alternative viewers: HTML, DHTML, stand-alone GUI application.

The OntoMap portal facilitates the evaluation and comparison of upper-level ontologies and lexical knowledge bases. It is based on unified representation of the resources, proprietary inference engine, and mapping methodology.

The inference engine is separately available as a Java library. It is currently being tuned for various applications including information extraction and information retrieval. Custom enhancements targeting specific requirements are possible.

The OntoMap Viewer is a stand alone Java Application , which represents the main functionality of the OntoMap web portal. OntoMap Viewer is distributed for all popular platforms: Windows, Linux, Solaris
