理想的Web IR服务模式的研究

1 引言信息检索(information retrieval,IR)指的是从一个文档集合中查找出包含有与用户的信息需求相关的信息内容的文档或文本。Web IR(Web information retrieval)指的是在Web环境下的IR问题。Web的出现,将含量、异构、动态数据的处理这样一个新的课题摆在了人们的面前。本文在分析了WebIR的特点,特别是Web用户信息检索的特点之后,从用户需求的角度,对架构Web IR的理想的服务模型提出了我们的一个构想,并分析了理想Web IR模式实现所需要的主要技术支持。

The Ideal Web IR Service Frame

Web IR presents a new challenge due to the heterogeneity,the dynamic characteristic and the size of the Web. A practical IR system that can satisfy the users' demand is very important ,in this paper we research the characteristics of Web IR in detail and give out the ideal Web IR service model:it should include search engine spectrum, search engine hierarchy,search engine cooperative network. We also analyze the key technique of this model,propose a simple way for the Web IR service to deal with the huge.scale of Web resources easily, and test part of the ideas in our prototype system SAInSE.
