A Pi-Calculus Based Ontology Change Management

Based on the pi-calculus, this paper proposes a kind of ontology process model used for solving the change implementation and propagation problems of ontology evolution process This solution is discussed at three levels: the change implementation of single ontology evolution, the push-based synchronization realization for the change propagation in the evolution of multiple dependent ontologies within a single node, and the pull-based synchronization realization for the change propagation of the distributed ontologies evolution.
