摘要:

在本文中,我们首先打开的重要问题,关于宾夕法尼亚大学韩国通用树库(PKT-UD),并解决这些问题,通过手动修改整个语料库的目的是生产更干净的UD注释,更忠实于韩国语法。为了与其他UD语料库兼容,我们遵循UDv 2指南,并广泛修改了词性标记和依存关系,以反映韩语的形态特征和灵活的词序方面。PKT-UD的原始版本和修订版本进行了实验与transformer为基础的分析模型,使用biaffine注意。在修改后的语料库上训练的句法分析模型显示出3.0%的显着提高标记的附件得分比以前的语料库上训练的模型。我们的错误分析表明,这一修订允许解析模型学习关系更强大,减少了几个要害差错,用于由以前的模型。

英文摘要:

In this paper, we first open on important issues regarding the Penn Korean Universal Treebank (PKT-UD) and address these issues by revising the entire corpus manually with the aim of producing cleaner UD annotations that are more faithful to Korean grammar. For compatibility to the rest of UD corpora, we follow the UDv2 guidelines, and extensively revise the part-of-speech tags and the dependency relations to reflect morphological features and flexible word-order aspects in Korean. The original and the revised versions of PKT-UD are experimented with transformer-based parsing models using biaffine attention. The parsing model trained on the revised corpus shows a significant improvement of 3.0% in labeled attachment score over the model trained on the previous corpus. Our error analysis demonstrates that this revision allows the parsing model to learn relations more robustly, reducing several critical errors that used to be made by the previous model.
