The measurement of second language (L2) productive lexical proficiency has driven a great deal of research over the past two decades. Research has indicated that more proficient speakers and writers tend to use a wider range of words and that more proficient writers tend to use words that are more sophisticated (less frequent in reference corpora). Research over the past 15 years has also demonstrated that the way words are used in context (i.e., collocation use) is also an important indicator of both written and spoken proficiency. In this study, we extend recent research that has modeled writing proficiency using collocation indices based on grammatical dependencies (e.g., verb–direct object) to spoken contexts. In particular, we model speaking proficiency scores from a large corpus of oral proficiency interview responses using a range of well-known indices of productive proficiency and newly developed grammatical dependency indices. The results indicated that all index types demonstrated small to moderate correlations with speaking proficiency individually but explained a large proportion of the variance when used in a multivariate model that included dependency collocation indices.

使用单词、二元词和依存二元词的使用特征来评估口语词汇和词汇语法熟练程度

在过去的二十年中，第二语言（L2）生产性词汇熟练程度的测量推动了大量研究。研究表明，更熟练的演讲者和作者倾向于使用更广泛的单词，而更熟练的作者则倾向于使用更复杂的单词（参考语料库中出现频率较低的单词）。过去15年的研究还表明，词语在上下文中的使用方式（即搭配使用）也是书面和口语熟练程度的重要指标。在这项研究中，我们将最近的研究扩展到使用基于语法依赖性（例如动词直接宾语）的搭配索引来模拟写作能力到口语上下文。尤其，我们使用一系列众所周知的生产能力指数和新开发的语法依赖指数，从大量口语能力面试回答中对口语能力分数进行建模。结果表明，所有指数类型均表现出与口语熟练程度的小到中度相关性，但在包含依存搭配指数的多变量模型中使用时，可以解释大部分方差。
