The Research On The Model Of Personal Knowledge Management Based On Hadoop

Personal knowledge management is a new research field generated with social development, whichhelps people manage the received information and data through techniques and instruments, and servespeople’s work and life better ultimately. With the advent of big data era, traditional personal knowledgemanagement system has certain defects in knowledge storage, security, retrieval, sharing and innovation.Cloud computing technology arises at the historic moment when the huge data information appears. It hasthe advantages of high efficiency on information storage and processing, especially the hadoop cloudframework has characteristics of open source, free of charge, stabilization and high efficiency. In this paper,we use the hadoop framework structures to build personal knowledge management platform, to solve theimpact on personal knowledge management platform because of enormous data. The platform is alsoimproved in terms of scalability, stability and safety.This paper mainly engages in theory and practice of personal knowledge management model.Theoretically in this paper we introduce the related concepts of the knowledge management and personalknowledge management, revealing the development and relationship of them. In addition, this paper alsodescribes cloud computing as well as the hadoop framework, analyze the effects of cloud computingexerting on personal knowledge management. And the key technology in the process of modelconstruction are also introduced, including the Lucene full text search framework, java language, anddevelopment of WeChat interfaceIn practice, this paper builds the model of personal knowledge management according to the designobjectives and requirements, and compares the personal knowledge management tools. Then it sums up thefour layer architecture of the proposed model and five basic function modules. The four layers include: thefirst layer of cloud server cluster, the second layer of hadoop framework layer, the third layer of applicationservice, the fourth layer of terminal. The five basic function modules includ knowledge storage, sharing,access system, knowledge retrieval and knowledge organization. At the same time, this paper also gives adetailed description of the model development environment, verifies the feasibility about the construction of hadoop distributed architecture, WeChat based knowledge sharing system and the Lucene full-textsearch engine.
