摘要：为测试网站的无障碍程度,需要测试网站中所有网页的无障碍性。对于大型网站,直接测试所有网页是耗时而昂贵的。在实践中,通常选择有代表性的样本进行测试,作为整个网站的测试结果。测试的结果完全依赖于所选择的页面,因此,采样方法不好可能会导致采样偏差过大,影响测试结果。为了解决这个问题,提出一种基于网页结构的抽取采样方法,以获得网站的评估结果。根据网页结构的相似性对整个网站进行分类,将网站无障碍测试转换为几类网页的评估,从而避免测试的高昂成本问题。实验结果表明,基于网页结构的网页抽样比现有的方法更精确,更好地反映了网站的无障碍水平。
In order to test the accessible level of website,it is necessary to test the accessibility of all webpages in website.For large-scale websites,the direct test for all webpages is time-consuming and expensive.In practice,some representative samples are usually chosen for test,whose result is taken as the test result of the entire website.The test result is completely dependent on the selected webpages,so the poor sampling method may lead to excessive sampling bias,and affect the test result.For the above problems,an extracted sampling method based on webpage structure is proposed to obtain the evaluation results of website.The sampling method based on webpage structure is to classify the entire website according to the similarity of webpage structure,transform the test of website accessibility into the assessment of various webpages,so as to avoid the high cost of the test.The experimental results show that the webpage sampling method based on webpage structure is more accurate than the available methods,and can better reflect the accessible level of the website.
