基于RSS的个性化信息服务系统研究

Research on Personalized Information Service System Based on RSS

针对现有个性化信息服务在动态性与时效性上存在一定局限性的问题,本文充分借助RSS信息聚合的能力,将RSS融合进个性化信息服务系统中,使得众多与用户需求相吻合的信息聚合在一起快速、动态地推送给用户。本文构建了基于RSS的个性化信息服务系统,其功能模块构成主要包括用户兴趣模型构建、资源推荐、RSS包装与信息服务推送,通过系统测试对本系统与人工操作结果进行对比,本系统在去重应用中的查准率为82.0%,查全率为92.2%,说明本架构与系统的可行性以及系统的有效性。

In view of the limitations of existing personalized information services in terms of dynamics and timeliness, this paper makes full use of the ability of RSS information aggregation to integrate RSS into personalized information service systems, which makes many match the needs of users. The information is aggregated together and pushed to the user quickly and dynamically. This paper constructs a personalized information service system based on RSS. Its functional modules mainly include user interest model construction, resource recommendation, RSS packaging and information service push. The system is compared with the manual operation results through system testing. The accuracy of the application is 82.0%, and the recall rate is 92.2%, indicating the feasibility of the architecture and system and the effectiveness of the system.
