当汉语的双音节词复合时，通常应用截断以产生从每个贡献词中提取一个音节的双音节输出，例如，下+fúd→ + →下fú。相当一部分新词是通过这个过程进入汉语的，所有四个基本音节的组合都在双音节新词中得到了证实。音节的基础逃脱截断的变化已被描述为任意的，但我们的分析揭示了一个明确的模式。信息音节得以保留。我们使用两个指标的信息量，组成家庭的大小和频率比的逻辑回归模型拟合中国截断模式。这两个因素都是重要的预测因素。为了进一步探索基于信息量的约束对表面形式的本质，我们分析了模型预测的截断概率为每个基地的新词语料库。随着截断概率的增加，模型的准确性也在增加。我们解释这个结果作为证据的约束调节的不确定性程度的基础截断映射。
When disyllabic words of Chinese are compounded, truncation often applies to yield a disyllabic output that draws one syllable from each of the contributing words, e.g., xiàdiē + fúdù → + → diēfú. A substantial portion of new words enter Chinese via this process, and all combinations of four underlying syllables are attested in disyllabic neologisms. Variation in which syllable of the base escapes truncation has been described as arbitrary, but our analysis uncovers a clear pattern. Informative syllables survive. We fit a logistic regression model to Chinese truncation patterns using two indices of informativity, constituent family size and frequency ratio. Both of these factors were significant predictors. To further explore the nature of informativity-based constraints on surface forms, we analysed the truncation probabilities predicted by the model for each base in the neologism corpus. As truncation probabilities increased so too did model accuracy. We interpret this result as evidence for a constraint regulating the degree of uncertainty in base-truncation mappings.
