Spoken and Written Vocabulary in High-stakes Assessments: The Impact of Lexical Choices at Different IELTS Proficiency Levels.

语料库分析已经在两个国际会议上发表演讲，发表论文和博士论文。我们目前的研究发现，词汇多样性（LD）测量预测手写论文的雅思成绩，但口语成绩单的LD不能预测雅思成绩。此外，在计算单词时，如果你将单词计数为引理、词源或单词族，结果会有所不同。

The corpus analysis has led to talks at 2 international conferences, a published paper and a PhD thesis. Our current findings are that Lexical Diversity (LD) measures predict the IELTS bands of hand-marked essays, but the LD of spoken transcripts do not predict IELTS bands. Also, when counting words, it makes a difference if you count words as lemmas, flemmas or word families.
