中文摘要：
标签技术如何与个人信息管理模型有机结合是个人信息空间管理系统中数据管理与共享的前提，针对传统个人信息管理中存在信息搜索效率低、无法共享的问题，提出基于标签埘组织本地数据，基于标签云组织全局数据的模型与算法，构建一个分布式、集成化的数据环境。系统性能测试结果表明，该算法能有效地提高个人信息空间管理系统的查准率，降低响应时间。
英文摘要：
In the presence of the networking environment, how to incorporate the tagging technique with the personal information management model can be tricky and the prerequisite of data management and sharing. According to the problems of the low efficiency and no sharing of information search in traditional personal infonnation management, this paper proposes a data model and algorithm based on Tag Tree to organize personal data in the Local PSI, and the other based on Tag Cloud to organize the data in Global PSI. Finally, this paper constructs a distributed and integrated data environment. The algorithm can improve the precision of the personal information management system, and reduce the responding time.
