摘要
随着网络信息的迅速膨胀,单个搜索引擎已不能满足用户的信息检索需求。元搜索引擎克服了传统搜索引擎查全率、查准率低的缺陷,能将用户的检索请求通过唯一的查询界面转发给多个独立的成员搜索引擎,并将所有查询结果进行融合处理后以统一的格式返回给用户。本文深入分析了元搜索引擎的实现原理及关键技术,并给出了元搜索引擎进一步的研究工作。
With the rapid expansion of network information, single search engine doesn＇t meet users＇ information retrieval requirement. Meta search engine overcomes the shortcoming of traditional search engine which has low query completeness and query precision. It sends users＇ search requests to underlying search engines through only search interface, and merges the results and then returns to the user. This paper analyzes the implement theory and key technique of meta search engine in detail, and puts forward more research contents about meta search engine.
