How Good is Your Wikipedia? Auditing Data Quality for Low-resource and Multilingual NLP aclanthology.org
AI Weekly's analysis →
  • MinHash deduplication removes 28.33% of all non-English Wikipedia articles, mostly from editions known to be dominated by bot-generated content.
  • Cited bot-content shares reach 99% for Cebuano, 90% for Waray and 68% for Swedish Wikipedia, per an Alshahrani et al. 2023 estimate.
  • Language models trained on the filtered Wikipedia largely match or outperform those trained on the raw dumps, with the biggest gains on lower-quality editions.

When transformers learn “impossible” languages, what do they learn? aclanthology.org
AI Weekly's analysis →
  • Janarthan, Haley and Goldwater train GPT-2 style models on perturbed 'impossible' variants of English and probe them beyond perplexity.
  • On BLiMP minimal pairs the models show only gradual degradation on impossible languages, mediated by information locality.
  • Generation is where the bias lives: the same models produce substantially fewer high-quality sentences at longer lengths.

Recent commentary

Pixel-based language models use rendered text instead of tokens. This could address several issues with tokenization, but how does adaptation work for such models? This is what we explore in our #EMNLP2026 paper, using Tibetan as a case study. A thread 🧵
