Digitizing construction method of large knowledge base system

The construction of large knowledge base tended to focus on the knowledge representation and reasoning mechanism, ignored the construction of knowledge sharing and exchange of the project. In this paper, the idea of knowledge digitizing representation, digitizing analysis, and the incremental method to construct a large knowledge base system is described. This paper presents practical large knowledge base system requirements and the hypothesis, and a simulation running and running states of the knowledge model. This paper also presents an example of application of two-states knowledge model. Finally, the digitizing points of engineering methods are summarized.
