号码百事通中个性化信息获取的几个基本问题研究

Research on Several Problems in Personal Information Retrieval of Best Tone Information Service

随着中国电信号码百事通业务的发展,个性化的信息获取越来越引起了人们的重视。为个人用户提供有针对性的个性化信息服务是未来信息服务的发展目标,但是关于个性化信息获取的特点、评价指标和获得这些指标所需的试验方法一直没有统一的定义。事实上,由于个性化信息获取的特点,传统的关于信息获取性能的评价和试验方法,并不适用于个性化信息获取的评价和检验。本文针对个性化信息获取的特点,提出了针对个性化信息获取的试验和评价方法,为个性化信息获取研究工作的开展,衡量和发现各个系统的不足,明确其改进方向,打下了一定的基础。

With the development of best tone information service, the personal information retrieval（PIR） has become more and more important. The most important goal of information service in the future is that to provide personalized information to the individual user. But, there isn＇ t an union definition of the characteristic, evaluation index, and the experiment method for the PIR. Actually, because the characteristic of PIR, the traditional evaluation index and experiment of information retrieval isn＇t fit for the PIR. According to the problem, we proposed evaluation index, experiment method, which will become the foundation of the PIR research, evaluation the different PIR systems, and focus on the improvement direction.
