The Discovery and Representation Methods of Expert Domain Knowledge Based On Knowledge Network

The paper is focused on the discovery and representation methods of expert domain knowledge based on knowledge network.Firstly the modeling method is discussed on the basis of knowledge relations,including the modeling methods of knowledge points and their inter-relations.Through the network analysis of the model,the Cliques and Sub-Cliques can be discovered,which can be used to discover Knowledge Cores and Sub-Cores through knowledge cohesion.Then the expert domain knowledge can be obtained and represented in structural domain knowledge network diagrams and knowledge(tables.) The methods are proved to be objective and precise,which is acknowledged in an application case.
