本研究分析了二语学习者在口语和书面语篇中的词汇水平。本研究旨在探讨词汇深度知识、词汇广度知识、核心词项通达性的分析性得分与词汇水平整体得分之间的关系。语料库的240个口语文本和240个书面文本产生的开始L2学习者，中级L2学习者，先进的L2学习者，和本族语者的词汇水平的分析和整体功能进行了评分由训练有素的评分员。使用多元回归分析，研究发现，搭配准确性，词汇多样性和词频是显着的预测人类的词汇水平的评价。搭配准确性解释了整体得分的最大差异（书面样本中为84%，口语样本中为89%）。作者讨论了搭配准确性在预测人类词汇水平判断中的重要性。
This study analyzes lexical proficiency in oral and written texts produced by second language (L2) learners of English. The purpose of the study is to examine relationships between analytic scores of depth of lexical knowledge, breadth of lexical knowledge, and access to core lexical items and holistic scores of lexical proficiency. A corpus of 240 spoken texts and 240 written texts produced by beginning L2 learners, intermediate L2 learners, advanced L2 learners, and native speakers were scored for both analytic and holistic features of lexical proficiency by trained raters. Using a multiple regression analysis, the study found that collocation accuracy, lexical diversity, and word frequency are significant predictors of human evaluations of lexical proficiency. Collocation accuracy explained the greatest amount of variance in the holistic scores (84% in the written samples and 89% in the spoken samples). The authors discuss the importance of collocation accuracy in predicting human judgments of lexical proficiency.
