- W2036083218 abstract "With the development of Internet technology, information resource is being spread widely, thus the issue of information overload formed. It becomes more difficult for users to retrieve their needed information from so enormous information space. To solve the issue of information overload, recommender system emerges as the times require. This paper presents the personalized e-Learning system using Collaborative Filtering Recommender Algorithm based on clustering of items. And the system will be implemented based on GWT with the advantages that developers can use only one language to develop web application. By the solution of GWT, the function of personalized information recommendation of e-Learning system will be achieved and personalized information will be recommended to users to help them improve learning efficiency. The results show that the solution of GWT is more flexible and simple, reduce the development cycle and cost, improved the real-time requirement of e-Learning system. Introduction With the development of Internet technology, huge information resources are presented to us constantly and are being spread widely. The scale of information resources in the internet is also growing, thus the issue of information overload formed. It becomes more difficult for users to browse all of the information resources and find out what they need or they are interested in. Recommender system is one of the solutions to facing information overload issue. It is an intelligent and personalized information service system and describes the user's long-term information need by user modeling, based on which it can customize the personalized information with the specific recommendation strategy [1]. In this paper, we will construct a personalized e-Learning system using Collaborative Filtering Recommendation Algorithm based on clustering of items and will implement the system based on GWT (Google Web Toolkit). For e-Learning system, the main benefit of Ajax is a greatly improved user experience. Although JavaScript and DHTML–the technical foundations of Ajax have been available for years, most programmers ignored them because they were difficult to master. So, if you're planning to use Ajax to improve only your application's user experience –if you're not also using it as a strategic advantage for your business–it may be unwise to spend a lot of money and time on the technology [2]. Aiming at the problems, the application framework of e-Learning system in this paper is implemented based on GWT which is a framework that developers use one language to develop web application. The project uses Java as a single programming language for both the client and server sides. According to the integration of GWT and Spring MVC, not only are the cost and complexity of e-Learning system reduced but the human-computer interaction experience and real-time requirements are improved effectively. GWT and Spring MVC Google offers a new framework named GWT to help Java developers create Ajax applications more productively. It uses Java as a single programming language for both the client and server sides. The Corresponding author. Tel.: +861-394-0536713; fax: +86-024-86592390. E-mail address: songbo63@aliyun.com. International Conference on Education, Management, Commerce and Society (EMCS 2015) © 2015. The authors Published by Atlantis Press 183 GWT eliminates the complexity of hand coding HTML, JavaScript, and other elements that bind the JavaScript actions triggered in an HTML page (client-side code run within the user's browser) to the controlling layer executing within the Java EE application server. When developers developed within a good IDE, the GWT can provide an immeasurable advantage over other frameworks and considerably lower the cost and complexity of the project. Spring MVC integrate in Spring Web Flow. Spring MVC separates the controller, the model object, dispatcher and the role of handler object. This separation makes them easier to customize. MVC is the core part of the WEB project development, as the decomposition of the three words, C (Controller) separate V (View, Client) and M (model, business) constitute MVC. The Spring annotations will make our work easier, by using the reflection mechanism of annotation to solve the problem of a large number of configuration. In the design of the architecture, the business developer only needs to develop five types of code: UIController, UIWidget, Action, DAO and Entity. UI using the GWT framework provides the UI development. The UI management components have cache management. It is mainly responsible for rendering and input control interface, and it does not call the background service. Besides it is mainly responsible for interactions with the data of the background services, management and scheduling Widget component. controller:UIController widget:UIWidget servlet:GWTSpringServlet action:Actionbase dao:Daobase" @default.
