Agent ontology systems interact with other agents via automated service discovery to share data and provide services on-the-fly. Resources need to be annotated with meta-data so that they can be correctly discovered and invoked. Ontologies provide shared conceptualization of a domain but it's not easy for everyone to agree on the same ontology for a domain. As such, ontology mapping becomes important to achieve compatibility. This is also true for security policies and so a refined algorithm for ontology mapping is very much desired; especially for WS-security. This paper highlights two semantic mapping frameworks for security policy ontologies i.e. SPD Ml framework and the dynamic MAFRA2 framework.
