摘要
利用层次分析法计算各层指标的权重,并用相对查准率等方法对最底层评价指标进行评分,最后综合权重和最底层评价指标的得分,定量评价Google,YAHOO,Baidu,SOHU4个综合性搜索引擎。结果表明,运用层次分析法定量评价搜索引擎的综合水平具有较强的科学性。
Google, YAHOO, Baidu and SOHU are quantitatively evaluated by an analytical hierarchy process to calculate the right - weight of each level and by a relative precision to score the bottom indices and comprehensive right - weight. The results indicate that the analytical hierarchy process is a scientific method for quantitatively evaluating search engines.
