Research on construction of the virtual dynamic knowledge discovery tree based on ontology reusability

The scope of ontology application is widespread, but even if in the same application field the emphasis points of different applications are different, the ontology which is suitable for some applications, but is not suitable for the other applications, this paper proposes a method of constructing knowledge discovery ontology tree for different applications based on the same ontology, it enhances the knowledge discovery accuracy rate, and enhances the reusability rate of ontology.
