Research on Knowledge Model for Ontology-Based Knowledge Base

摘要

The robust knowledge base needs a reasonable design pattern to represent knowledge model. On the foundation of the research about relationship of knowledge model with knowledge ontology, the knowledge model defined by three categories of domain knowledge, reasoning knowledge and task knowledge is set up. Furthermore, the matching relationship mechanism of knowledge model with knowledge base is put forward. At last, according to design pattern of knowledge model, the example of knowledge base for project risk management based on ontology is implemented.
