A Graph-based Coarse-to-fine Method for Unsupervised Bilingual Lexicon Induction (2020.acl-main)
Copied to clipboard
| Challenge: | Recent methods for bilingual lexicon induction are based on unsupervised cross-lingual word embeddings . previous methods only use word-level information, which is limited and inaccurate . |
| Approach: | They propose a graph-based approach to induce bilingual lexicons in a coarse-to-fine way . they use word cliques from graphs and aligned clique-level words to find initial translation solution . |
| Outcome: | The proposed method improves the performance of bilingual lexicon induction compared with previous methods. |
A Resource-Free Evaluation Metric for Cross-Lingual Word Embeddings Based on Graph Modularity (P19-1)
Copied to clipboard
| Challenge: | Cross-lingual word embeddings encode the meaning of words from different languages into a shared low-dimensional space. |
| Approach: | They show that modularity can be used to improve unsupervised word embeddings . they show that it is useful for low-resource languages where one often has few bilingual pairs . |
| Outcome: | The proposed model improves unsupervised cross-lingual word embeddings on distant language pairs in low-resource settings. |
