Bilingual Lexicon Induction via Unsupervised Bitext Construction and Word Alignment (2021.acl-long)
Copied to clipboard
| Challenge: | Existing methods for bilingual lexicon induction are linear and require simplifying assumptions. |
| Approach: | They propose methods that combine unsupervised bitext mining and unsupervised word alignment to produce higher quality lexicons. |
| Outcome: | The proposed method outperforms the state-of-the-art on the BUCC 2020 task by 14 F1 points . further analysis suggests they are comparable quality . |
A Simple Approach to Learning Unsupervised Multilingual Embeddings (2020.emnlp-main)
Copied to clipboard
| Challenge: | Recent work on unsupervised cross-lingual embeddings in the bilingual setting has given the impetus to learning a shared embeddable space for several languages. |
| Approach: | They propose to solve two sub-problems together to learn a shared embedding space for several languages. |
| Outcome: | The proposed approach outperforms existing methods in bilingual lexicon induction, cross-lingual word similarity, multilingual document classification, and multilingual dependency parsing tasks. |
