Length-aware Byte Pair Encoding for Mitigating Over-segmentation in Korean Machine Translation

ACL 2024findings

Byte Pair Encoding is an effective approach in machine translation across several languages. However, our analysis indicates that BPE is prone to over-segmentation in the morphologically rich language, Korean, which can erode word semantics and lead to semantic confusion during training. This semant…

Leveraging Pre-existing Resources for Data-Efficient Counter-Narrative Generation in Korean

COLING 2024main

Counter-narrative generation, i.e., the generation of fact-based responses to hate speech with the aim of correcting discriminatory beliefs, has been demonstrated to be an effective method to combat hate speech. However, its effectiveness is limited by the resource-intensive nature of dataset constr…

Translation of Multifaceted Data without Re-Training of Machine Translation Systems

EMNLP 2024finding

Translating major language resources to build minor language resources becomes a widely-used approach. Particularly in translating complex data points composed of multiple components, it is common to translate each component separately. However, we argue that this practice often overlooks the interr…
