Design And Implementation Of Online Learning And Communication System Based On Personalized Recommendation Algorithm

In recent years, with the rapid development of the Internet, online learning has become more and more popular, however, the network resource overload phenomenon has appeared at the same time with the blowout development of the Internet, so people have to look for the resources they needfrom the massive resources. However, e-commerce platform based on the personalized recommendation is more and more mature, so the system can recommend the goods to the users through the analysis on the behavior of individuals, and in the future, with the more and more resources of the network in the world, the online learning and personalized service will become a development trend of the Internet.In this paper, online learning and communication system based on a personalized recommendation algorithm is designed.At first, the related technologies of Java Web and the personalized recommendation algorithms are studied briefly. Secondly, through the demand analysis of on-line learning and communication system and application analysis of personalized recommendation algorithm, the overall framework of the system is designed.Thirdly, according to the analysis of the overall framework of the system and the user's demand, online learning communication system is divided into different functional modules, in each function module, give full consideration to the users' experiences, besides, every module is analyzed in detail,and the corresponding database is designed in detail. After the completion of the each functionalmodule's design, each function one by one is realized by the Java Web technology and personalized recommendation algorithm, for example, user login, web page, campus news, curriculum center, resource download, interactive communication, personal center and so on. Recommended course module based on the personalized recommendation algorithm as user's personalized settings embedded into the course, resources, downloads and individual function module, and then the generated data is stored in the database according to the design pattern of the database.Finally, each module of the system was tested,and a comprehensive test of the online learning and communication system is carried outby writing the test cases, then the test results are given to ensure that the system is safe and stable in operation.In addition, this system adopts three tier network architecture,and the traditional development mode based on B/S mode is already very mature. And it has the advantages of simple development, strong sharing, simple and convenient maintenance, convenient operation, high security and reliability. So this system has wide application and safety reliability.Thispaper presents the online learning and communication system based on personalized recommendation algorithm will recommend the effectively resources to users according to the analysis of users' behaviors and preferences, besides, this system provides an online learning and communication platform, the users through the system can realize the online learning, online download, online communication and recommended curriculum view and so on. In one word, it's an online learning platform with personalized service, this system conforms to the development trend of the Internet online learning, its feasibility and practicability is wide.
