ABSTRACT:
A method, apparatus, and program product is provided for constructing a domain-specific ontology for interpreting a policy. A phrase assumed to be associated with a policy is received. An indefinite term in the phrase is identified. Internet searches are performed on a plurality of terms from the phrase. A plurality of potential replacement terms is extracted from the Internet search results for the indefinite term. A context-specific ontology is built for the indefinite term based upon tracked occurrences of the plurality of potential replacement terms. The policy is interpreted by accessing the domain-specific ontology to interpret the indefinite term, where the indefinite term is interpreted by mapping the indefinite term to a plurality of potential replacement terms in the ontology for a plurality of contexts, and creating a policy based upon the interpretation of the indefinite term from the ontology.
