User-oriented model of ontology evolution
一种面向用户的ontology进化模型

By now,many industrial and academic applications have adopted ontology as their conceptual backbone,and the ontology evolution becomes the key to these applications.A four-phase evolution process was proposed,which was composed of change request,change capture,change implementation and exception handle.The main contributions of this model are:dynamic adaptation of the ontology-based system to the changes in the exterior environment and easy control of the evolution process.
