Research And Design Of Online Cosmetic Supervision System Based On Web Crawler And Short Text Similarity

In the new era,the national economy has developed rapidly and the living standard of the people has been steadily improved,online shopping has become the most popular shopping method of the moment.As a daily necessities,cosmetics are increasingly in demand.However,there have been continuous explosions of counterfeit cosmetics incidents on online shopping and have attracted widespread attention.Therefore,it is particularly important to improve the regulation of online sales of cosmetics.In order to strengthen the awareness of self-discipline and integrity of enterprises,and facilitate the supervision department to regulate the online cosmetics,a set of online cosmetics supervision system is designed.First of all,from the background and significance of the research,this thesis analyzes the advantages and disadvantages of the current cosmetic supervision system and the research status of related technologies at home and abroad,so as to determine the content and research methods of the thesis..Then the related technology is introduced.On the basis of the analysis of the T-mall web page URL and the features of the Bloom Filter,the link filter module in the network crawler is improved to reduce the error caused by the misjudgement rate of Bloom Filter,so that it is more suitable for this system.Then,based on the actual demands of the system,the thesis carries out requirement analysis and system design.Through the analysis of the user's rights and operation process,the function of the system is defined and the UML modeling tool is used to model the system.The related use case diagram is drawn.Based on the above requirements,the system framework is determined,the detailed design of the functional modules and the design of each module database are completed.Finally,Visual Studio 2012,SQL Server 2008 R2 development tool,C#,IIS,.NET Framework and other technologies are used to encode and deploy the network cosmetics supervision system.At present,the function of the system has been completed,and the expected results have been basically achieved.Information collection,comparison and coding schemes are feasible...
