Description

UD_Korean-KSL is a dependency treebank of second-language (L2) Korean.

The treebank contains 12,977 sentences—10,323 in the training set, 1,311 in the dev set, and 1,343 in the test set. These sentences are sourced from two datasets: (1) the Kyung Hee dataset, with sentence IDs starting with “KH” and annotated with classroom proficiency levels (A1–C2); and (2) the KoLLA dataset, with sentence IDs starting with “KL” and grouped as fb (foreign beginners), fi (foreign intermediates), and hb (heritage beginners).

Acknowledgments

We acknowledge the original data contributors: the Kyung Hee dataset (credit to Jungyeul Park and Jung Hee Lee; note that this dataset is no longer maintained and its sentences are no longer used for further annotation) and the KoLLA dataset (credit to Markus Dickinson, Ross Israel, and Sun-Hee Lee). We also acknowledge our annotators: Hee-June Koh, Chanyoung Lee, and Youkyung Sung.
