According to an exemplary embodiment of the present invention, a method for managing a resource using an apparatus for managing a resource is provided. The apparatus for managing a resource generates a first instance for a first community using a first ontology class about communities including at least one resource as a member according to a goal. The apparatus for managing a resource generates a second instance for a first resource using a second ontology class about resources. Further, the apparatus for managing a resource estimates a relation between the first instance and the second instance.
