基于语料库的区域CxGs方言计量变体研究
Finding Variants for Construction-Based Dialectometry: A Corpus-Based Approach to Regional CxGs
摘要：
本文开发了一种基于构造的方言测量法，能够识别以前未知的构造，并测量给定构造的区域变化程度。其中心思想是使用构式语法归纳来学习构式语法（CxG），然后将这些构式作为方言计量的特征。这提供了一种方法，用于测量区域CxG之间的聚合相似性，而不限制在事先的一组结构的变化。学习CxG的评价是如何以及它描述了举行了测试语料库，而方言的评价是如何以及它可以模拟英语的区域品种。该方法使用两个不同的数据集进行测试：第一，国际语料库的英语代表八个外圈品种;第二，网络爬行语料库代表五个内圈品种。结果表明，该方法（1）产生了一个质量稳定的语法跨子集的一个单一的语料库，是（2）能够区分英语的区域变体之间的准确度高，因此（3）支持方言测量方法测量英语变体之间的相似性和（4）测量的程度，每一个结构是受区域变化。这对认知社会语言学很重要，因为它使构式之间的竞争在功能层面上组织起来的想法可操作化，因此方言测量需要代表尽可能多的可用功能空间。
英文摘要：
This paper develops a construction-based dialectometry capable of identifying previously unknown constructions and measuring the degree to which a given construction is subject to regional variation. The central idea is to learn a grammar of constructions (a CxG) using construction grammar induction and then to use these constructions as features for dialectometry. This offers a method for measuring the aggregate similarity between regional CxGs without limiting in advance the set of constructions subject to variation. The learned CxG is evaluated on how well it describes held-out test corpora while dialectometry is evaluated on how well it can model regional varieties of English. Themethod is tested using two distinct datasets: First, the International Corpus of English representing eight outer circle varieties; Second, a web-crawled corpus representing five inner circle varieties. Results show that themethod (1) produces a grammar with stable quality across sub-sets of a single corpus that is (2) capable of distinguishing between regional varieties of Englishwith a high degree of accuracy, thus (3) supporting dialectometricmethods formeasuring the similarity between varieties of English and (4) measuring the degree to which each construction is subject to regional variation. This is important for cognitive sociolinguistics because it operationalizes the idea that competition between constructions is organized at the functional level so that dialectometry needs to represent as much of the available functional space as possible.
