摘要
针对当前网络搜索引擎未能较多地关注用户需求、查全率与查准率不高、彼此间不兼容的缺陷,提出建立基于用户需求的元搜索引擎,并分析其基本原理,给出其基本结构,讨论其运行机制和关键技术。指出基于用户需求的元搜索引擎可使网络信息资源在一定程度上结构化,实现网络信息资源的自组织。
By discussing the deficiencies of the current network information retrieval (IR) and the search engine, the paper proposed that a Meta search engine should be made on the basis of the users' information needs. Then the primary structure of the Meta search engine is given, and the retrieval process and key technologies are discussed. At last, the significance of Meta search engine is presented.
