Library New Directions in Knowledge Management：Recycling of technical design research of virtual and reality knowledge space

Objective: This paper focus on some new directions about management of library knowledge with a new environment including cognitive knowledge space, knowledge management technology, knowledge resource, knowledge service. It gives library profound change on entity knowledge space and virtual knowledge space and explains Internet technology, Internet plus, media tools, big data sets and others. This can re-shape the foundation,technology, tools and method to change to the new direction of knowledge management for layout library knowledge space, the means of use knowledge, information management tools and service object. Method: Compare the changes and needs of the entity and virtual knowledge space and to reconstruct the knowledge space through reconstruction. It can analyze the theory and tools of modern information technology in virtual reality and use big data knowledge space to gather and coordinate the development of entity knowledge space. Results: Virtual knowledge space management has the demand to access the accurate knowledge data rapidly with the ability to efficiently analyze large amounts of data, finding professionalanalytical methods and tool, the means of clean interpretation of serious of big data. Using available tools and methods get the evaluation results of the assessment of knowledge acquisition and reliable demand through econometric analysis. This change directly affects the Internet plus network as use tolls and collaborative control strategy. Entity space mainly as the sensory design and implementation and also focus on the timeliness of reality. Virtual space mainly use the knowledge-based data to effectively use the physical space. The actual examples shall prevail. Findings and Value: Through the study of virtual and physical library knowledge and expounds the resource possession system of the new type library. The internal relations and external influences between big data analysis, library collection and use control mechanisms, also analysis the main factors and indicators affecting library and development of knowledge resource.Construction knowledge management and control system based on virtual environment and big data set using toll model experience and have further research on the strategy of spatial reengineering of knowledge management. Example: knowledge management of Library
