Design And Implementation Of E-Commerce System For Second-Hand Car Based On Collaborative Filtering

With the development of domestic automobile industry and the increase of new car ownership,the acceptance of second-hand cars by buyers has been greatly improved,which jointly promotes the rapid and steady development of second-hand car market.With the continuous improvement and breakthrough of information technology such as the Internet,the competition in all walks of life in the current society has shown a fierce trend,especially in automobile sales,so e-commerce has become the most important means of automobile sales.However,the second-hand car market is faced with the problem of information overload due to the large number of second-hand cars and different vehicle conditions.It is often difficult for users to quickly select the desired vehicles.Users provide a used car e-commerce platform that can realize personalized recommendation.It not only provides users with one-stop service from all aspects of car selection,purchase,use,replacement,maintenance,etc.,but also provides users with intelligent recommendation,vehicle sales and evaluation services.This paper mainly introduces the design and implementation of e-commerce system based on collaborative filtering.This paper discusses from four aspects:requirement analysis,overall design,detailed design and implementation,system test,etc.The system is designed based on MVC application mode and developed with SSM framework.At the same time,Solr search application server is used to provide search service for the system.Collaborative filtering recommendation algorithm is used to realize the recommendation of used car service,and mahout framework is used to realize the recommendation algorithm.In the design and implementation of the project,I mainly participated in the vehicle management module,the second-hand car information maintenance,second-hand car information management and other functions;in the second-hand car search module,keyword search,label search,label sorting and other functions;at the same time,I also participated in the analysis,design and implementation of the second-hand car recommendation function.In automobile e-commerce,we use the current advanced information technology to solve the relevant problems,so as to reduce the unnecessary cost during the sales period,not only to improve their business value and business activities,but also to bring great convenience to users.From the current use of the project,we can see that the personalized service mode of automobile e-commerce is very suitable for thecurrent choice of consumers and the needs of the enterprise society,and has a very high value for consumers,enterprises and society.
