摘要:

我们引入了一个图多项式区分树结构来表示依赖文法和一个基于多项式表示的度量来量化语法相似性。多项式编码关于句子中单词的依赖结构和依赖关系的准确和全面的信息。我们采用基于多项式的方法来分析并行通用语义树库中的句子。具体来说,我们比较句子的语法和它们在不同的语言中的翻译,我们进行了一个句法类型学研究的并行通用的同源性树库中的可用语言。我们还展示和讨论了该方法在语料库句法多样性测量方面的潜力。

英文摘要:

We introduce a graph polynomial that distinguishes tree structures to represent dependency grammar and a measure based on the polynomial representation to quantify syntax similarity. The polynomial encodes accurate and comprehensive information about the dependency structure and dependency relations of words in a sentence. We apply the polynomial-based methods to analyze sentences in the Parallel Universal Dependencies treebanks. Specifically, we compare the syntax of sentences and their translations in different languages, and we perform a syntactic typology study of available languages in the Parallel Universal Dependencies treebanks. We also demonstrate and discuss the potential of the methods in measuring syntax diversity of corpora.
