Korean constituency parsing benefits from fine-grained morphological data

By PulseAugur Editorial · [1 sources] ·

Researchers have compared three different representations for parsing Korean constituency structure, focusing on how to best handle the complex nature of Korean words (eojeols). The study evaluated parsers using Morpheme+XPOS, Eojeol+XPOS, and Eojeol+UPOS representations derived from the Penn Korean Treebank. Results indicated that while eojeol terminals simplify transition sequences, the Eojeol+UPOS representation significantly underperformed compared to morphologically richer conditions. The Morpheme+XPOS representation yielded the strongest parsing results, even when projected to the eojeol domain, suggesting that fine-grained morphological and XPOS information is highly beneficial for constituency parsers.

IMPACT This research offers insights into optimal data representation for natural language processing tasks, potentially improving the performance of parsers for morphologically rich languages.

    Representing and Parsing Korean Constituency Structure at Different Levels of Granularity

    arXiv:2608.27035v1 Announce Type: new Abstract: Korean constituency parsing raises a representational challenge because the terminal units of a phrase-structure tree do not straightforwardly correspond to simple surface words. Korean eojeols are morphologically complex spacing un…
