本研究的重点是通过一个简单的效率原则：依存局部性来解释语序的语法共性和语序的数量偏好。在其最简单的形式中，依存局部性认为，在句法依存关系（任何中心词依存关系）中链接的单词应该在线性顺序中接近。我们给大规模的语料库的证据，依赖本地预测词序在语法和用法，超出了预期的独立动机的原则，并展示了一种手段，在语料库研究中分离语法和用法。最后，我们讨论了以前没有记录的依赖长度的变化，以及它如何与其他语言特征，如头部方向，提供了一个丰富的未来的语言学理论。
This work focuses on explaining both grammatical universals of word order and quantitative word-order preferences in usage by means of a simple efficiency principle: dependency locality. In its simplest form, dependency locality holds that words linked in a syntactic dependency (any head-dependent relationship) should be close in linear order. We give large-scale corpus evidence that dependency locality predicts word order in both grammar and usage, beyond what would be expected from independently motivated principles, and demonstrate a means for dissociating grammar and usage in corpus studies. Finally, we discuss previously undocumented variation in dependency length and how it correlates with other linguistic features such as head direction, providing a rich set of explananda for future linguistic theories.
