The Knowledge Management System Based On Cloud Computing

According to "The revitalization plan of cultural industry", the established market-oriented cultural industry development mode. It is not only the important way to meet people’s diversified needs of spiritual and culture, but also to promote the adjustment of economic structure and Changing the mode of economic development. At present, the key tasks is establishment of a modern cultural market system and development of emerging cultural industries. With the era of piece reading coming, the reader on knowledge acquisition precision, professional knowledge and to manage the knowledge demand grow with each passing day. But the manufacturers who can provide professional knowledge and accurate knowledge cannot meet this in the present. The current cooperation of the publisher and the knowledge service providers still stay old way that the publisher provide Electronic publication, the knowledge service providers build knowledge database by copy for readers searching and download. This mode reduces the efficiency of knowledge flow, hinder the transfer of information between the various roles in the industry chain, with the industrial development. So it is necessary to build a new industry model, to meet contemporary people on the piece information acquisition, management and restruction of the knowledge, knowledge creation, information behavior information and circulation and can collect users’ in the industrial chain, data mining. This pattern is the reader centered of publish and distribution model. The realistic meaning of it lies in that it is an effective integration of readers, knowledge service providers, publishers, and quickly turn knowledge into productivity tool.This paper researched and developed a knowledge management system based on cloud computing. This paper researched and developed a knowledge management system based on cloud computing.This System use J2EE and adopt C/S combined with B/S architecture. Using Struts、Spring、Hibernate implementation of the B/S MVC model. Implementation of SOA by the CXF component of Apache.Using Json data format for passing information between different system. Using the MongoDB that one of NOSQL database for text information saving and searching.The system also uses data extraction, OLAP and other computer technology. Implementation of RDBMS and NoSQL co storage function, automatic text classification function, data mining, information push function, the function of knowledge management and knowledge reconstruction.Achiving the purpose of information sharing between the publisher and ther knowledge Service providersr,improve the knowledge production, publishing, marketing, distribution all this process management, meet the reader’s demand of the knowledge management, Knowledge Reconfiguration and Knowledge Innovation.Through trial operation, the system achieved the expected goal.The publisher and the knowledge service can synergistically Knowledge Publishing and distributing, and adjust the publishing content based on user behavior analysis.The readers can read better accurate and more professional knowledge, reconstructed knowledge and the Innovation of knowledge through this system.
