A semantic unification approach for M2M applications based on ontology

M2M (Machine-to-Machine) technology makes it possible to network all kinds of terminal devices and their corresponding enterprise application servers. Nowadays, M2M platform, working as a mid-workstation, collecting raw data from terminals through 3G wireless techs and then transferring them to enterprise applications, has been popularly utilized by several enterprise applications. However, it still has difficulty in information sharing among different terminals and enterprise applications when transferring data because of the distinguished usage of business vocabularies. Hence, this paper puts forward a core business vocabulary (CBV) mapping approach based on Multi-Domain Ontologies that can lead to semantic unification when M2M platform dispatches the data among terminal devices and enterprise application servers, in order to make it easier to share information among each other. Moreover, we implement a CBV mapping module which is integrated into the work M2M Middleware and then put in practice.
