Design And Implementation Of Group-buying Platform Based On Social Network Service

Presently, credibility problems of electronic commerce have attracted much attention. As a new model of electronic commerce, group-buying’s characteristics includes data burst, extensive wide, and high discount. However, it still confronts with serious credible problems. One way to improve the reliability of transactions on open platform is to construct a reputation system based on social networks, in order to evaluate service credibility and anticipate future behavior of service providers. Aiming at resolving low credibility of current group-buying websites, a user-oriented credible, sharable, and directionally transmitted portal group-buying platform is designed are implemented. Based on the concept of social networking, the platform integrates a novel group-buying recommendation model and optimizes group-buying navigations through characteristics of social networks. Then requirement analysis, design and implementation are introduced. Contents of this thesis are shown as followed.Firstly, we introduce related technical background of this project, including basic knowledge of group-buying navigation platform, research investigations, theoretical foundation of social network, Web 2.0and other main techniques, etc. Theory and practical foundations for appearance of social group-buying portal is analyzed based on above analysis.Secondly, a novel group-buying recommendation model based on social network is proposed. This model integrates many effect factors, such as social relationships strengths among users in social networks, shopping experience of friends, historical transaction records and so on. Based on the factors, decision function computes credit correlations of users in social group-buying networks. Simulation and experiment are adopted to verify feasibility and effectiveness of the model.Thirdly, a group-buying portal platform with sociality attributes based on the novel model is constructed. The platform mainly consists of four function modules:profile management, friend relationship management, products information management and transaction information management. This paper mainly describes requirement analysis, detailed design, and functional implementation of this system, including function description, system flowchart, user interface design, Message Sequence Chart (MSC), and so on.After that, the test and demo environments of social group-buying portal platform are addressed, and then test cases and related results are described.Finally, this paper states the shortage of this project and work requiring improvement, and then summarizes all work and achievements of the author during the master period.
