A Study on Universal Dependency Annotation for Korean

The purpose of this paper is to find a methodology for parsing Korean by the method of 'Universal Dependencies'. Universal Dependencies expresses the annotation marking system that can be applied to the formal patterns and syntactic relationships of various types of languages. The UD project presents a framework for consistently annotated multi-lingual treebank corpus for various languages around the world through the 'CoNLL shared task' and is currently applied to more than 50 languages. This flow has a great influence on research related to not only the UD project itself but also the syntactic annotation for individual languages, and efforts are being made to apply the universally dependent syntax analysis marking system in the UD according to the characteristic of the individual language. When annotation labels cannot be applied due to the nature of the Korean language in consideration of compatibility, they need to be excluded. Among DEPREL labels, several labels are difficult to apply in Korean when looking at the specific items. In this paper,, DEPREL overall annotation system of UD was translated and a representative category of elements that needed to be transformed was selected to discuss the actuality of linguistic convergence and its application.
