An example method for facilitating network control and management using semantic reasoners in a network environment is provided and includes generating a fully populated semantics model of the network from network data according to a base network ontology of the 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. In specific embodiments, generating the model includes 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.
