A Corpus-based Syntactic Analysis of Two-termed Unlike Coordination (2021.findings-emnlp)
Copied to clipboard
| Challenge: | a phenomenon of language that conjoins two or more terms or phrases using a coordinating conjunction is still largely elusive and widely debated amongst linguists. |
| Approach: | They propose to use a computational corpus-based approach to study two-termed unlike coordinations where the two conjuncts of the coordination phrase form valid constituents but have distinct categories. |
| Outcome: | The proposed analysis shows that the two conjuncts within unlike coordinations display different properties based on their position, supporting an antisymmetric view of the structure of coordination. |
Phonemes to the Rescue: Multilingual Tokenization Based on International Phonetic Alphabet (2026.acl-long)
Copied to clipboard
| Challenge: | Widely-used subword tokenization approaches favor high-resource languages and tokenizer-free methods yield longer sequences for scripts with a higher bytes-per-character ratio. |
| Approach: | They propose to use the International Phonetic Alphabet (IPA) as a language-agnostic input representation for multilingual tokenizers. |
| Outcome: | The proposed model improves tokenization quality and generalizes more effectively to unseen languages and scripts. |
False Friends Are Not Foes: Investigating Vocabulary Overlap in Multilingual Language Models (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Prior work has shown that token overlap facilitates cross-lingual transfer or introduces interference between languages? |
| Approach: | They devised a controlled experiment where they train bilingual autoregressive models on multiple language pairs under systematically varied vocabulary overlap settings. |
| Outcome: | The proposed model outperforms models with disjointed vocabularies on XNLI and XQuAD and shows that token overlap is beneficial for multilingual tokenizers. |
