搜索引擎评价指标体系的建立与应用

The Establishment and Application of Evaluation Criteria System for Search Engines

本文结合搜索引擎的特点,采用网上特尔菲法进行专家调查以确定搜索引擎评价的各项指标,并利用基于指数标度的层次分析法确定各项指标的权重,从而构建搜索引擎评价指标体系.在此基础上,以构建的搜索引擎评价指标体系作为评价工具,同样运用基于指数标度的层次分析法作为评价方法,选择若干中文搜索引擎作为评价对象,进行实证分析.结果表明综合评价性能最优的搜索引擎是Google简体中文.

According to the features of search engines, this paper establishes a set of evaluation criteria system for search engines by using Delphi Method online, and calculates the weight of these evaluation criteria by Analytic Hierarchy Process （AHP） based on exponential scale. It also selects several Chinese search engines as the objects, does empirical analysis based on this criteria system using the same method. The result shows that Google is the best search engine on the comprehensive pedormance level.
