摘　　要：文章在概念抽取算法基础上,提出一种基于概念的元搜索引擎体系结构。这种体系结构提供统一的用户界面,通过查询适配可以同时使用多个独立搜索引擎的高级搜索功能。并且通过概念抽取对搜索结果进一步分析,使其更为准确和详细。系统提供了概念图这种独特的结果显示方式,引导用户细化搜索范围以得到更为精确的结果。In this paper,based on the concept extraction algorithm, we propose a concept-based meta search engine infrastructure. Uniform user interface and search adaptation are provided, which allow users to try advanced search of multilde search engines without detailed knowledge. Concept extraction is also used for further result analysis, which makes search results more accurate and helpful. Moreover, the infrastructure provides a unique output method, concept map, which can significantly narrow the result scope and produce more precise result.

关 键 词：元搜索引擎 概念抽取 相关度排序
