Web-based Discount Online Shopping System Design And Implementation

Web-based discount online shopping system，is built on a web-processing techniquesusing Chinese major e-commerce sites on the Internet to crawl down each product categoryproduct information, and then classify and organize, which the implementation providingusers complete product information, quickly and easily find deals in general merchandiseshopping information platform. Greatly facilitate the users to get a different product dealse-commerce website platform in a website which the user can save shopping time with agreater degree of digging deals.The work of this paper mainly has the following points:(1)In this paper, there are two main functions,product information and offers commodityrecommend what used the web pages related crawled technology and and Chinese textprocessing technology, from an engineering point of view of Item Information serviceplatform for the requirements analysis and system design.(2)By studying other major e-commerce sites commodity classification structure, build acomprehensive, systematic Product information classification trees, convenient for the user toprovide disaggregated basis under Categories to achieve commodity classification accordingto three categories in the preceding Home Show.(3)Using a strategy based on a custom implementation of commodity information networkreptiles custom crawl, based on Jaccard distance local sensitive hash algorithm text similaritycalculation method for text clustering algorithm. At the same time, the use of text s imilaritycalculation method to achieve automatic text-matching of user browsing history andcommodities information. Users browsing history will be clustering similar items together,and recommended to the user content. Enabling users to save shopping time, precisepositioning needs of users, increased commodity trading success rate, and can seek businessopportunities for small and medium e-commerce site to promote online and offline modes ofcooperation.(4)In this paper, we design structural framework based on fullly net purchase user needs analysis and rigorous analysis of the entire system needs.System used the idea of a layeredarchitecture, separating each functional block of the system, making the system coupling low,conducive to add or delete features，and simple and convenient secondary development.
