Domain knowledge centered knowledge discovery process model
一种以领域知识为中心的知识发现过程模型

Considering the problems in actual application, this paper proposed a kind of domain knowledge centered know-ledge discovery process model, then formalized it and described its dynamic semantics. Compared with the known knowledge discovery process model, the model expressed the hypostasis of the knowledge discovery process more exactly and had a strict formalization base, which provides a new reference for the design of knowledge discovery system and actual application.
