OntoMap: portal for upper-level ontologies

Currently the evaluation of the feasibility of general-purposeontologies and upper-level models is expensive mostly because oftechnical problems such as different representation formalisms andterminologies used. Additionally, there are no formal mappingsbetween the upper-level ontologies that could ease any kind ofstudies and comparisons. We present the OntoMap Project(http://www.OntoMap.org), a project with the pragmatic goal tofacilitate the access, understanding, and reuse of such resources.A semantic framework on the conceptual level is implemented that issmall and easy enough to be learned on-the-fly. We tried to designthe framework so that it captures most of the semantics usuallyencoded in upper-level models. Technically, OntoMap is a web-siteproviding access to several upper-level ontologies and manualmapping between them.
