【摘要】：随着搜索引擎在信息化生活中的指导作用越来越强,建立完整的评价体系已经成为搜索引擎优化的基础。本文从搜索引擎评价体系的现状入手,结合搜索引擎特点,采用定性和定量相结合的分析方法,排除相关性高的指标,确定最终索引数据库性能、检索效果、用户便利度三大类13个评价指标。在此基础上,运用基于比例标度的层次分析法(Analytic Hierarchy Process,AHP)构建层级结构,借鉴专家意见确定评价指标的权重;结合TOPSIS法(Technique for Order Preference by Similarity to an Ideal Solution)进行评价指标数值的规范化处理并排序计算,构建了较为完整的评价体系。选择四大热门中文搜索引擎作为评价对象,进行实证分析,结论表明,本文所述评价指标体系和方法思路可行,有较强可操作性和指导作用。
[Abstract]:With the guidance of search engine in information life, the establishment of a complete evaluation system has become the basis of search engine optimization. This paper starts with the present situation of search engine evaluation system, combines the characteristics of search engine, adopts qualitative and quantitative analysis method, excludes the index with high correlation, determines the performance of final index database, and determines the retrieval effect of the final index database. User convenience three categories of 13 evaluation indicators. On this basis, the scale-based Analytic hierarchy process (Analytic Hierarchy Process,AHP) is used to construct the hierarchical structure, and the weight of the evaluation index is determined by using expert opinions for reference. A relatively complete evaluation system is constructed by normalizing and sorting calculation of evaluation index value with (Technique for Order Preference by Similarity to an Ideal Solution) method of TOPSIS. Four popular Chinese search engines are selected as the evaluation object, and the empirical analysis shows that the evaluation index system and method mentioned in this paper are feasible, and have strong maneuverability and guiding function.
