The design and implement of domain knowledge search system based on semantic;

Representation of domain knowledge in situation assessment;

Construction and application of domain knowledge based on knowledge tree;

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.

This paper aims at the disadvantage of remote sensing visual judgement ,imports the conception of field knowledge,converts the visual and semantic knowledge into digital information and makes many research on the auto-matic recognition of the objects style in the image.

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.

The form and mechanism of inference of information understanding,semanteme structure of rule knowledge and production process of new knowledge is discussed ;the memory matrix、computation rule of semanteme truth value and confidence factor of recognition reasoning are established.

Learning algorithm model of constructive PONN based on knowledge rules;

After analyzing the defect and shortcoming of current pipeline check software,the domain-driven design method and UML are introduced to review the check rules,then the pipeline check knowledge rule base capable of customization and its reasoning engine are put forward,finally checking the all-sided investigation pipeline data and its vector data combining with GIS intelligently is realized.

Aim at the workflows as be modeled with knowledge rules,how to keep the reliability of the user defined knowledge rules,workflow model,simulation platform building and simulation engine are studied in this paper,find out the bugs by using visual instance display and statistic technic.
