Researchers have developed PETRA, a novel dataset and pipeline designed to improve information retrieval in the petroleum engineering domain. This system addresses the scarcity of domain-specific relevance labels by transforming noisy public web text into a curated corpus with synthetic supervision for dense retrieval and reranking. PETRA's construction involves high-recall energy-domain curation, an accurate energy-domain classifier, query generation, and LLM-written hard negatives, resulting in significant improvements in retrieval accuracy and reasoning-intensive tasks.
