Cross-Linguistic Syntactic Difference in Multilingual BERT: How Good is It and How Does It Affect Transfer? (2022.emnlp-main)
Copied to clipboard
| Challenge: | Multilingual BERT (mBERT) has demonstrated considerable cross-lingual syntactic ability, but it is not well understood what leads to this variation and whether it fairly reflects difference between languages. |
| Approach: | They propose to use multilingual BERT to enable zero-shot cross-lingual transfer of syntactic knowledge between different languages by generating grammatical relations in 24 different languages. |
| Outcome: | The results show that the distance between the distributions of different languages is highly consistent with the syntactic difference in terms of linguistic formalisms. |
