Since the middle1990s, the concept of social network, tools, and techniques to develop and gradually increasingly mature, the advent of the Internet social network technology and user behavior to the real society to promote social form, virtual community and realistic community started to cross. More and more information service organizations and institutions began to realize through social networking technology to improve the level of information service and performance. Knowledge on the one hand, users are constantly changing information environment and information requirements, information service is required to provide a more comprehensive and high quality information service, the library, the pressure forced it to consider to carry out knowledge community information service to adapt to the social development needs the network environment. Library itself, on the other hand, knowledge information service, the adjustment of business model, is also directly contributing to the library to build community in order to realize the network knowledge information service.Basic idea of this paper is around the library knowledge community information service implementation encountered many problems, we will focus on analysis and solve these problems, promote the implementation of library knowledge community information service. Key content includes library knowledge community evolution mechanism, framework model, knowledge community library knowledge community platform building and the library knowledge management, etc. The attached figure53vice, table15. Full of about150000words, which is divided into seven parts, the main content is as follows:Part1discusses the community information service of library knowledge related theoretical issues. Library knowledge background has a certain community, and is the result of many factors jointly promote. Focused on the definition of library knowledge community, the theory source, and analyzes the evolution paths of library knowledge community, further defined the connotation of library knowledge community and analyses the complex evolutionary mechanism of library knowledge community. Part2analyzes the social network environment on library knowledge demand guidance, adapt to the need of the process of library knowledge community information content and feature and innovation of library knowledge oriented community service requirements.Part3discusses the function orientation and objective orientation of library knowledge community.analyze the knowledge points out that the library community building elements include the main body factor, organizational factor and environmental factor three aspects. On this basis, put forward the technical support of library knowledge community..Part4analyzes Analysis technique is presented based on the open platform of library knowledge community technology condition, secondly according to the social networks to build PHP+MYSQL UChome characteristic, and has independent and open features of more flexible and powerful roaming application, that its structure is ideal to build library knowledge community service architecture method, through the analysis of UChome platform architecture, using the MVC pattern, namely Model (the Model), View (View) and control (Controller) to gradually realize the function module and show its execution, and put forward the library knowledge community platform for mobile users of technical scheme and implementation process.Part5is Based on the above, on the basis of the research content, proposes to build social knowledge community library under the network environment of operation and management mechanism, including the knowledge community alliance set up plan and how to effectively for performance evaluation of library knowledge community.Part6is Knowledge of community service platform, wuhan university, for example, analysis of the SNS, and sina weibo application environment and the present situation and the knowledge of community service platform, based on this, analyzes its existing problems and proposes the solution countermeasure.The last part summarizes this dissertation, and points out the inadequacies in this research and makes a prospect of the knowledge innovation-oriented, Library knowledge of community information services.
