本文提出了一种分析带有短语标注和语法功能的不连续短语结构表示的新技术。短语结构表示被转换为具有复杂边缘标签的依存关系表示,这使得推导出一个既具有短语标签又具有语法功能的依存句法分析模型成为可能。我们对德国的Tiger Treebank和瑞典的Talbanen05 Treebank进行了评估,并报告了这两个数据集的竞争结果。
This paper presents a novel technique for parsing discontinuous phrase structure representations, labeled with both phrase labels and grammatical functions. Phrase structure representations are transformed into dependency representations with complex edge labels, which makes it possible to induce a dependency parser model that recovers the phrase structure with both phrase labels and grammatical functions. We perform an evaluation on the German TIGER treebank and the Swedish Talbanken05 treebank and report competitive results for both data sets.
