13. The apparatus of claim 12 , wherein controlling and managing the network comprises: detecting inconsistency in network data based on rules specified in the base network ontology, wherein an appropriate action is triggered upon detecting the inconsistency; inferring logical consequences based on a set of asserted facts, wherein another appropriate action is triggered when an error is inferred; and verifying satisfiability of a concept for service composition and resource identification, wherein a report on degree of deviation between a request and current network state is generated if the concept's satisfiability is not verified.
12. An apparatus in a computer network, comprising: a memory element for storing data; and a processor, wherein the processor executes instructions associated with the data, wherein the processor and the memory element cooperate, wherein the apparatus is configured for: generating a fully populated semantics model of the computer network from network data according to a base network ontology of the computer network, wherein the semantics model comprises a representation of the computer network in a framework of semantically related terms comprising properties of network features of components of the computer network; mapping the fully populated semantics model to a network knowledge base; feeding contents of the network knowledge base to a semantic reasoner; and controlling and managing the network using the semantic reasoner, wherein generating the fully populated semantics model of the network comprises: receiving the network data from the network; parsing the network data; loading the parsed network data into in-memory data structures; accessing a manifest specifying binding between a network data definition format and ontology components of the base network ontology; identifying ontology components associated with the network data based on the manifest; and populating the identified ontology components with individuals and properties from the corresponding data structures; wherein the network data definition format comprises a selection from a group consisting of Structure of Management Information (SMI), YANG, and Extensible Markup Language (XML); and wherein the manifest comprises: mapping of at least one of SMI managed object, YANG leaf and XML element to a Web Ontology Language Description Logics (OWL-DL) class to which an individual belongs; mapping of at least one of SMI object hierarchy, YANG leafref and XML element hierarchy to an OWL-DL object property asserted over a pair of individuals; mapping of a value of at least one of SMI object, YANG leaf and XML element to an OWL-DL individual of a corresponding class; and asserting a data property on an individual.
