OntoMap: facilitating easier access, understanding and comparison of the existing upper-level models (Cyc, SENSUS, WordNet, EuroWordnet, SIMPLE, GUM)

(Atanas Kiryakov, OntoText Lab., Sirma AI Ltd.)

The goal of the project is to facilitate an easy access, understanding, and reuse of upper-level and general purpose ontologies as well as lexical knowledge bases. The guideline of OntoMap is that currently the evaluation of the existing upper-level models is too expensive mostly because of technical problems such as different representations and terminologies used. Additionally, the situation could be improved by making available formal mappings between the upper-level ontologies that will make easier any kind of comparative studies.

Technically the result will be a web site that provides a number of upper-level ontologies and mappings between them in a number of different formats - PROLOG, KIF, SQL, OIL, XML, etc. An application server will be developed giving a uniform access to the resources via widely accepted standards such as OKBC (on a semantic and pragmatic level) and RMI, SOAP, and CORBA (on implementation level). A conceptual model (meta-ontology) will be developed inspired by the property classification of Guarino and Welty, ODE (Methontology) and Cyc. All the ontologies and mappings will be classified according to the KIF (ANSI draft proposal) conformance dimensions.

After the end of the project the server will be further supported and developed by OntoText Lab. Paid services for ontology conversion, classification, hosting and mapping based on OntoMap will be provided for both upper-level and domain specific ontologies.
