| Challenge: | Byte Pair Encoding (BPE) is an effective approach in machine translation across several languages, but it is prone to over-segmentation in Korean, an agglutinative and morphologically rich language. |
| Approach: | They propose a new method that incorporates long words into the Korean vocabulary by strategically preserving morphological information and reducing semantic confusion. |
| Outcome: | The proposed method outperforms BPE and surpasses state-of-the-art morpheme-aware tokenization methods. |
