Design And Implementation Of Specific Promoting Advertisement Subsystem Of Agricultural Product Quality Tracing System

Because food safety crises occur frequently, implementing quality traceability of agricultural products has become one of the trends in international trade development. An agricultural product quality traceability system not only can provide healthy agricultural products for the masses, but also can enhance the competitiveness of the high quality agricultural products in the market.Advertisement recommendation about agricultural information is an important part in implementing quality traceability of agricultural products, because it can improve people’s ability to acquire agricultural information they need. So the main content of this thesis is on the design and implementation of a specific promoting advertisement subsystem, which is a part of agricultural product quality tracing system. And the advertising cross recommendation module is the core module of the subsystem. The advertising cross recommendation module runs the BI-Polar slope one algorithm and the recommendation algorithm based on item attribute to make advertisement recommendation. In this way, the subsystem can help consumers to acquire the agricultural product information they probably need.The main research works in this thesis are as follows:(1) Briefly in application background about specific promoting advertisement subsystem of agricultural product quality tracing system and the research of recommendation systems at home and abroad.(2) A brief review on the knowledge of collaborative filtering based recommendation technology、the slope one algorithm and the recommendation algorithm based on item attribute which the thesis will use to help develop the specific promoting advertisement subsystem. Beside, by analysing the characteristic of different cross recommendation algorithm to explain why use these two algorithms as the core algorithm to make recommendation compute in the thesis.(3) Using object-oriented analysis, designing thoughts to help design and implement the specific promoting advertisement subsystem. Specifically, using the systems function chart and UML use case diagram to analysis the system requirements, using the system architecture diagram, UML package diagram and the network deployment diagram to make a outline design for the subsystem, using the UML sequence diagrams, UML class diagram for the subsystem detailed design, and using the flow chart to describe the implementation of cross recommendation algorithm of the subsystem. In the end, demonstrating the condition of subsystem operation and evaluating the operating results to describe the implementation of the subsystem.
