Domain ontologies have become very important elements in healthcare informatics. Ontological interoperability is crucial to the success of healthcare information system through semantic web[l]. As the ontologies differ, resolution of semantic differences between them is an active research area. Software agents can be deployed in various ways to automate this resolution of semantic differences. Approaches for semantic mapping of ontologies through conversation between software agents include: (1) Dialogue game loosely modelled on human communication [2]; (2) Dialogue game based framework with an explicit modelling of mental states in terms of the beliefs and of the participating software agents and their goals[3]. (3) Use of lexicons such as worldnet to retrieve alternative forms of a concept in the ontology and use the alternate forms for mismatch resolution through ontology negotiation protocol (ONP)[4] and associated extensions [5].
