The paper briefly reviews the practice of western urban planning profession from the view of the changing domain of the profession, the identity crisis of urban planning profession and planner s special knowledge domain.

In the paper, unstructured data, such as papers published by experts and subjects committed by experts, is mined to recognise the knowledge domain of experts automatically.

It is provided with important practical meaning that probes into the knowledge domain and course architecture of network engineering (NE) specialty for cultivating applicational-type professionals, and for constructing its teaching criterion and improving its quality of education and teaching.

0)hasbeen established, the focus of investigation should be turned to the task of field knowledgeacquisition.

On the basis of expounding the importance of knowledge representation method, combined with the representation method of field knowledge, knowledge representation of the hypertext of cognition for computer foundation course has been designed out, meanwhile, implementation model has been given out.
