Knowledge Cognitive Navigation System Based On Network Construction

The importance of knowledge is obvious in this knowledge economy era. But the knowledge structure of human being is so complicated that it is easy for people to be lost during the course of study and to go through many twists. As a result, it is difficult to establish a reasonable knowledge structure.Based on the relevant theory and method of the knowledge management, knowledge engineering and knowledge visualization and the related instrument of information technology, we may help people establish a good knowledge structure in the study to achieve the optimization of learning.Firstly, the article analyzes the existing cognitive situation for subject specialized knowledge and proposes an idea of "Knowledge Cognitive navigation" and provides theoretical support for it through the knowledge management theory and related learning theory.Then the article establishes the frame for the "Knowledge Cognitive Navigation" system in terms of knowledge-expressive method, and explores the application of its central part, the discipline knowledge map, in the education.Finally it takes the subject Application Electronic Technology for example and developed a "Discipline Knowledge Cognitive Navigation" systematic model by means of information technology. It aims at making the learners comprehend the systematic structure of the whole subject knowledge, know their own position in this system and make clear the channel to attain the expected cognitive height, thus realizing the leading role of Discipline Knowledge Cognitive Navigation for learners' study.
