SCRIPT: A Subcharacter Compositional Representation Injection Module for Korean Pre-Trained Language Models

ArXi:2604.12377v1 Announce Type: cross Korean is a morphologically rich language with a featural writing system in which each character is systematically composed of subcharacter units known as Jamo. These subcharacters not only determine the visual structure of Korean but also encode frequent and linguistically meaningful morphophonological processes. However, most current Korean language models (LMs) are based on subword tokenization schemes, which are not explicitly designed to capture the internal compositional structure of characters.
