The information retrieval community has recently witnessed a revolution due to large pretrained transformer models. Another key ingredient for this revolution was the MS MARCO dataset, whose scale and diversity has enabled zero-shot transfer learning to various tasks. However, not all IR tasks and domains can benefit from one single dataset equally. Extensive research in various NLP tasks has shown that using domain-specific training data, as opposed to a general-purpose one, improves the performance of neural models. In this work, we harness the few-shot capabilities of large pretrained language models as synthetic data generators for IR tasks. We show that models finetuned solely on our unsupervised dataset outperform strong baselines such as BM25 as well as recently proposed self-supervised dense retrieval methods. Furthermore, retrievers finetuned on both supervised and our synthetic data achieve better zero-shot transfer than models finetuned only on supervised data. Code, models, and data are available at https://github.com/zetaalphavector/inpars .

    cs.IR 2025-05 conditional novelty 6.0 of 10

    Using direct preference optimization with reranker or GPT-3.5 preferences to align synthetic query generation improves downstream dense retrieval effectiveness on MS MARCO and TREC-DL.

  6. RaDeR: Reasoning-aware Dense Retrieval Models

    cs.CL 2025-05 conditional novelty 6.0 of 10

    A math-trained dense retriever and reranker, built from MCTS reasoning trajectories and self-reflection, outperforms strong baselines on reasoning-intensive retrieval benchmarks and beats BM25 on chain-of-thought queries.

  7. Scaling Search Relevance: Augmenting App Store Ranking with LLM-Generated Judgments

    cs.IR 2026-02 conditional novelty 5.0 of 10

    Using a fine-tuned 3B LLM to generate millions of textual relevance labels for App Store search improves the ranker's behavioral/textual Pareto frontier and lifts conversion by 0.24%.
