Research On Virtual Community System For Large-scale Production Of Rice

With the rapid development of the Internet,people exchange information more and more conveniently,and more agricultural practitioners exchange information and share knowledge through the Internet to improve production efficiency.The combination of Internet information technology and agricultural industry has promoted the process of agricultural informationization.As a manifestation of agricultural informatization,the large-scale production virtual community system of rice provides an information exchange platform for rice practitioners.Farmers applying virtual community systems can meet their needs in the network environment to make up for the lack of traditional communication methods,and enhance their production technology capabilities and promote healthy and sustainable development of rice production through exchanges and learning with other farmers and rice experts..The work of this thesis relies on the key project of the national key R&D project “Food High-yield,Efficiency and Scientific and Technological Innovation”.The 2017 project“Study on the key technologies and model construction of the water-efficient and efficient synergy and disaster prevention and control of high-yield festivals in the middle and lower reaches of the Yangtze River”(Project No.: 2017YFD0301500)Part of the neutron project "Development of Rice Production Process Monitoring and Intelligent Service Platform"(No.:2017YFD0301506),a large-scale production of remote information services for rice.Based on the research on the existing virtual community situation at home and abroad,this paper proposes the construction principle centered on farmers,with the goal of open access,interaction,collaborative learning and knowledge sharing,combined with forum,knowledge retrieval and online communication.Construct methods to establish a virtual community for large-scale production of rice.The main work is as follows:(1)In order to solve the problem that the traditional virtual community trust system is not comprehensive and the user viscosity is low,from the three aspects of technical trust,institutional trust and interpersonal trust,by creating a trust model with node transitivity,combined with mutual evaluation and online reputation evaluation.And a reasonable trust value algorithm,which effectively enhances the user’s trust in the virtual community.(2)Research on knowledge,knowledge sharing and knowledge sharing process,and analyze the interaction and communication between the members of the virtual community to transfer each other’s knowledge into their own knowledge.By building a knowledge base and knowledge map of the virtual community,community members can acquire knowledge effectively and quickly.(3)Through the functional analysis of the virtual community,based on the characteristics of large-scale production of rice,using micro-service architecture and integrating various security mechanisms and caching mechanisms,a set of virtual community systems with simple operation and stable performance were designed and developed.
