【摘要】 随着Internet的飞速发展及其技术的不断更新,教育信息化将不断深入,对教育资源及其平台提出了更高的要求。面对浩如烟海杂乱无章的资源,传统的以用户主动寻找资源为主的被动服务模式,越来越难以满足用户个性化需求行为,教育资源库的建设需从传统的用户寻求信息转变为资源库主动推送信息的模式,即将原有的信息pull模式转变为push模式,增加为用户提供个性化服务的功能。本课题以全国最大的省级教育资源库之一——上海教育资源库为背景,结合笔者在上海教育资源库的实习工作和实践,研究面向教育资源库个性化服务技术及其应用。通过研究并运用Web2.0中支持个性化服务的技术,在上海教育资源库的核心基础平台分布式资源管理平台上构建一个支持其管理的资源个性化使用的技术模块——个性化知识门户系统。个性化服务技术的运用完成了系统个性化界面定制和个性化内容定制等关键功能的实现:RSS技术支持实现了系统的个性化内容定制功能,完成用户所定制的个性化内容在资源库里的聚合;Ajax技术支持实现了系统的个性化界面定制功能,为用户提供丰富良好的使用体验。基于个性化服务技术的个性化知识门户系统的设计和实现,将有效地打破原有资源库以用户主动寻找资源为主的被动服务模式,采用主动引导用户,把满足用户个性化需求的知识以主动推送模式传送给用户,真正实现以用户需求为中心的服务模式,从而有效提高上海教育资源库及其核心基础平台分布式资源管理系统的服务质量和资源使用效率。论文主要分为五部分:第一章介绍了论文的研究背景,通过对上海教育资源库软件平台及其核心基础平台分布式资源管理平台的分析,提出了分布式资源管理平台的新需求,并引入以个性化服务为核心的Web2.0的先进理念,最后提出论文的研究目标与内容,及研究的意义。第二章是对Web2.0中支持个性化服务关键技术的研究,详细介绍了实现个性化服务功能的XML、RSS以及Ajax等关键支撑技术。第三章是对基于个性化服务技术的个性化知识门户系统的整体设计,包括系统整体架构设计、各功能模块介绍、面向教育资源库个性化服务的关键功能描述以及系统开发环境和部署环境的介绍等。第四章是对个性化服务关键技术的实现,通过运用Web2.0中的支持个性化服务的关键技术RSS技术和Ajax技术,重点对个性化知识门户系统中的个性化界面定制和个性化内容定制等关键模块加以实现。第五章对已有工作进行了总结,在取得成果的同时,列举了下一步研究的方向。更多还原

【Abstract】 With a rapid development of Internet and its constantly upgraded technology, there is a growing need for educational informationalization with an even higher demand for educational resources and their platform. Amidst the boundless resources, the traditional way of the passive service model, by which the users have to look for resources by themselves, is no longer able to satisfy the users’ individualized demands. Consequently, the educational resources center should be transformed from such traditional model, in which the users search for information by themselves, into a new model, in which the resources center delivers the information actively to users. In other words, it is a transformation from a "pull" model into a "push" model, which enhances the center’s ability to offer the users individualized services.Based on one of the largest provincial-level educational resources center nationwide—Shanghai Educational Recources Center (SHERC), as well as the author’s internship and practice at SHERC, this essay studies the technologies and their application for individualized services of educational resources center. By analysis and use of the technologies of Web2.0 that support the individualized services, a technological module is aimed to be established on the distributed educational resources platform of the core platform of SHERC, which will support the individualized use of resources—an individualized knowledge portal system. The application of the individualized service technologies fulfills such key functions as setting the individualized interface and contents of the system. RSS technology realizes the setting of the system’s individualized contents, which clusters those individualized contents set by users in the resources center; while Ajax technology makes the setting of an individualized interface successful, which enables the users to enjoy a rich and sound using experience. The design and fulfillment of an individualized knowledge portal system based on individualized service technologies, will break through the traditional passive service model which is characterized by user’s searching for resources by themselves. Instead, a new model will be established by guiding the users actively, and delivering to users the knowledge that meets their individualized demands, so that a service model centering on users can be achieved, with the service quality and the resources utilization efficiency of the distributed resources management system of the core platform of SHERC enhanced.The essay is divided into five chapters as follows: Chapter One introduces the background of the study. Through an analysis on the the distributed resources management platform of the core platform of SHERC, a new demand for the distributed resources management platform is proposed, with the advanced conception of Web2.0 focusing on the individualized serviced introduced. Finally, the objectives and contents of the essay are posed, followed by the significance of the research.Chapter Two studies the key technologies of Web2.0 that support the individualized services, with a detailed exploration of key supportive technologies that realize the function of individualized services such as XML, RSS, and Ajax, etc.Chapter Three layouts a whole design of an individualized knowledge portal system based on individualized service technologies, including the framework of the system as a whole, an introduction of the functions of the module, a description of key functions for the individualized services of educational resources center, and an introduction of the system’s development and deployment environment, etc.Chapter Four achieves the key technologies for individualized services. By using the key technologies of Web2.0 that support the individualized services such as RSS, Ajax, etc., an emphasis is laid on working out such key modules as setting the individualized interface and contents of the individualized knowledge portal system.Chapter Five concludes the achievements of this study, with the future direction of research introduced.更多还原
