RelEx-PT

Dataset Summary

RelEx-PT, a new sentence-level Relation Extraction dataset for Portuguese. Addressing the scarcity of high-quality, controlled resources for the language, RelEx-PT provides a balanced benchmark comprising 18 Wikidata-derived relation types across diverse domains. The dataset is built through a distant supervision pipeline that links Wikidata triples with Portuguese Wikipedia sentences and enhanced by a Natural Language Inference (NLI)-based filtering process, combining scalability with quality assurance.
