既有的外语测试信度估计方法大多基于测试分数,属测后估计,信度证据容易受到无关因素的污染,估计结果并不可靠;而基于语料库的信度估计方法则是基于测试文本,属测前估计,信度证据不受其它因素污染,估计结果较为可靠;通过对我国权威性外语测试考研英语阅读理解试题进行横向和纵向复本信度估计,能够证明这种基于语料库的去污染信度估计方法的可靠性和可行性.本研究的价值在于从语料库语言学视角为外语测试的信度估计开拓新途径.

The present reliability estimating methods, using the test score as reliability evidence which is easily polluted by irrele- vant factors, is a post-test estimation and thus can hardly obtain reliable results; the reliability estimating method from the perspec- tive of corpora, using the test text as reliability evidence which is unpolluted, is pre-test estimation and can get reliable results. This paper, through estimating the parallel reliability horizontally and vertically by employing corpora linguistic method, verifies that reli- ability estimation using the corpora linguistic method is valid and practical. The value of this study is to blaze new paths for reliabili- ty estimation of foreign language tests from the corpora linguistic perspective.
