The Key Technology Research Of Knowledge Tree Management Subsystem Based On Knowledge Dimension Model

With the coming of the knowledge economy era, knowledge, as one of thecore resource in our society, makes knowledge management get more and moreattention. The goal of knowledge management should be achieving the virtuousloop between the knowledge and knowledge owner, while the current knowledgemanagement researches put more focus on knowledge’s description andorganization neglecting the importance of knowledge owner. Knowledgedimension model proposed by Tsinghua University has already enhanced theimportance of knowledge owner, however, with the rapid development ofknowledge mining and recommendation, how to promote the generation of newknowledge and spreading between knowledge owners is becoming an importantsubject of knowledge management besides the basic content of managingknowledge for owners. In short, under the current environment, the dynamicknowledge management is a develop direction for knowledge managementinevitably.Based on the theoretical research of knowledge management, dimensionmodel, knowledge tree and knowledge recommendation, according to thepresent situation and development of knowledge management, the articleproposes the knowledge tree management model based on knowledge dimensionto improve the dimension model and take a try in dynamic knowledgemanagement. Firstly, based on the overall model design, the article gives thedetail function design of knowledge tree model from the sub-model of personalknowledge tree management model, public knowledge tree management modeland related knowledge tree recommendation. Then it established the knowledgemanagement mechanism of knowledge tree management model from knowledgeorganization, transactions between knowledge and self-growing of knowledge.To ensure the reliability of our model, the article accomplishes the relatedalgorithms research on public knowledge tree extraction and related knowledgetree recommendation. On the one hand, using the genetic algorithm andstatistics, it realizes the public knowledge tree extraction algorithm. On the other hand, based on the popular knowledge recommendation technic, it designsthe related knowledge dimension and knowledge tree recommendation. It alsodoes the feasibility and efficiency analysis of algorithms with the valid test data.In the end of the article, it designs a knowledge tree management systembased on dimension model with the system’s function structure and softwarestructure to verify the validity of our model. It does the system development inwhich we mainly implemented the knowledge tree model system on the basis offundamental functions of knowledge management system based on dimensionmodel. With the valid data testing and analysis in higher education information,we finally proves the effectiveness and applicability of the knowledge treemanagement model.
