O’Donnell et al. (2013) considered four measures of formulaicity and reported that they produced different results concerning the effects of expertise and first/second language status on formulaic sequence usage in academic writing. The current study explores several additional methodological issues using the same dataset from O’Donnell et al. (2013). We first motivate the need for criterial consistency and investigate whether frequency- and association-based measures yield different results when they are both obtained using corpus-internal criteria. The informativeness of the diversity dimension of formulaic sequence use is then gauged by comparing the results of phrase-frame type-token ratio against those of other measures. Finally, we profile formulaic sequence distribution across quartiles of different measures to assess the effect of variable measure thresholds. Our findings highlight the criticality of issues of criterial consistency, formulaic sequence diversity, and threshold variation in formulaic language research.

调查标准一致性、多样性维度和公式化语言研究中的阈值变化的影响

奥唐纳等人。(2013) 考虑了四种公式化措施，并报告说它们在专业知识和第一/第二语言状态对学术写作中公式化序列使用的影响方面产生了不同的结果。当前的研究使用来自 O'Donnell 等人的相同数据集探索了几个额外的方法论问题。(2013)。我们首先激发对标准一致性的需求，并研究当使用语料库内部标准获得时，基于频率和关联的度量是否会产生不同的结果。然后通过将短语框架类型令牌比率的结果与其他措施的结果进行比较来衡量公式序列使用的多样性维度的信息量。最后，我们分析了不同度量的四分位数之间的公式序列分布，以评估可变度量阈值的影响。我们的研究结果强调了标准一致性、公式序列多样性和公式语言研究中的阈值变化问题的重要性。
