基于元搜索引擎的多关键词检索技术
The Technology of Multi-keyword Information Retrieval Based on Meta-search Engine
【摘要】 文章根据主要中文搜索引擎Google和Baidu对多关键词的查询处理存在的缺陷,提出了“核心关键词”的概念和“分级权重”的计算方法;并进而提出了将基本搜索引擎搜索结果与网页内容分析合并相关度算法和元搜索引擎的准确度偏差评价公式。研究表明,元搜索引擎不但消除了死链接和重复链接,而且准确度偏差与Google和Baidu相比,分别减少7.26%和12.47%,准确度得到了一定提高。
【Abstract】 As to the retrieval drawback of the major search engines,Google and Baidu,this paper proposes a new method of meta-search engine to improve the retrieval performance.The meta-search engine establishes the“kernel key-word”and“multi-level weight ”concepts,and adopts the algorithm of integrating the results from basic search engines with the web page contents.This paper develops a correctness derivation evaluation formula for the meta-search engine.The meta-search engine not only overcomes the dead-link and repeated-link,but also improves the retrieval correctness by7.26%and12.47%respectively when compared with Google and Baidu.
