A contextual and semantic analysis of network entities facilitates a mapping and comparison of the entities between network models. The system includes a plurality of refine handler and match handler pairs that use rules that are specific to the type of network entities being analyzed. The refine handler analyzes the network model to identify the entities for which its rules apply, and the match handler processes these identified entities to establish a pairing between corresponding entities in each model. A sequence of refine-match processes are applied to the network models, typically in accordance with a hierarchy of rules until each entity is identified as a matched, added, or removed entity. A difference handler processes the identified pairings to provide a difference analysis that facilitates a meaningful interpretation of the configuration changes, and a user interface provides an interactive environment to view the differences from different perspectives.
