摘要:

本文提出了一种利用交互语法从短语结构层次句法分析中提取依存结构的方法。交互语法是一种用极性系统来表达词与词之间的交互作用的形式主义。极性的饱和导致了句法结构的变化。成分之间发生相互作用,但随着语法的词汇化,这些相互作用可以在单词层面上进行翻译。依存关系是从解析过程中提取的:每个依存关系都是极性饱和的结果。我们得到的依赖关系可以看作是通常的依赖树的细化。总的来说,这项工作揭示了短语结构和依存句法分析之间的联系。

英文摘要:

This article proposes a method to extract dependency structures from phrase-structure level parsing with Interaction Grammars. Interaction Grammars are a formalism which expresses interactions among words using a polarity system. Syntactical composition is led by the saturation of polarities. Interactions take place between constituents, but as grammars are lexicalized, these interactions can be translated at the level of words. Dependency relations are extracted from the parsing process: every dependency is the consequence of a polarity saturation. The dependency relations we obtain can be seen as a refinement of the usual dependency tree. Generally speaking, this work sheds new light on links between phrase structure and dependency parsing.
