New pipeline curates 41B token European Portuguese web corpus for LLMs

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new pipeline for curating high-quality web corpora specifically for European Portuguese (PT-PT). This pipeline addresses challenges like dialectal overlap with Brazilian Portuguese and the scale of data processing. It efficiently processes 411 TB of raw data, incorporating a novel post-scraping block that improves document yield by 19.04% by preventing premature discarding of valid text. The framework includes rigorous language identification, weighted fuzzy deduplication, and neural quality classification, resulting in a clean and representative corpus suitable for LLM pre-training. AI

IMPACT Provides a scalable framework and a clean corpus optimized for LLM pre-training, potentially improving model performance on European Portuguese.
