基于用户体验的谷歌和百度搜索有效性比较研究

为评估搜索引擎的有效性,采用问卷调查法请211名中国用户基于11项指标评估谷歌和百度两大中文搜索引擎.因素分析结果显示11项指标可以聚合为内容准确性和内容直接性两个因素,由两者构成的搜索有效性模型具有良好的信度和效度.应用该模型评价谷歌和百度的搜索有效性发现,谷歌在搜索内容准确性方面优于百度,而在搜索内容直接性方面则不如百度,内容直接性体验上的不足导致谷歌的总体搜索有效性低于百度.两个搜索引擎的用户体验模式也存在明显差别,用户对谷歌有效性的感知主要来自内容准确性,而对百度有效性的感知则相对均衡的来自内容准确性和内容直接性两个方面.

Comparative study on search effectiveness of Google and Baidu based on user experience

To evaluate the effectiveness of search engines,211 Chinese users were surveyed to assess two major Chinese search engines Google and Baidu based on 11 items.Factor analysis results showed that the 11 items could be clustered into two factors,named contents accuracy and contents accessibility respectively,which formed a search effectiveness model with high reliability and validity.Then the model was applied to compare the search effectiveness of Google and Baidu,and found that Google was better in contents accuracy while worse in contents accessibility,and its inferior in contents accessibility caused its lower total effectiveness score than Baidu.There were also significant differences between the two search engines in user experience pattern.Users＇ effectiveness perception to Google was mainly derived from contents accuracy,while their effectiveness perception to Baidu was derived relatively from both the factors.
