Knowledge Management In Knowledge Supply And Demand To Match The New Methods And Case Studies

The management of explicit knowledge using computer technology is the research emphasis of knowledge management. Pointing to different types of users, how to provide users with most suitable knowledge in the shortest time is one of research subdivisions of knowledge management, which is the knowledge search.The commodity supply and demand matching in the tangible market is used for reference and the basic ideas and methods of knowledge supply and demand matching are discussed to solve the problem of knowledge search. Different types of users are able to precisely search the knowledge of specific domain and depth in the knowledge base (KB), and adjust the knowledge amount "exposed" to them.Firstly, from the knowledge demand view, the characteristics of the knowledge users and basic methods of gathering user grade are analyzed. Secondly, from the knowledge supply view, the concept of knowledge cell is discussed and the document attributes in the matching solution are analyzed. Thirdly, the so-called fit degree and fit degree matrix are discussed to describe the rationale of knowledge supply and demand matching. Furthermore, the entire design and implementation process of knowledge supply and demand matching based on an instance is discussed, including instance project introduction, knowledge base design and implementation, document management system and document fit degree management system implementation, middle layer operation process and user interface design. Lastly, it summarizes the jobs the paper has done, focuses the prospect of knowledge search that should be done in the future and gives the essential program text of the system implementation.
