| Abstract | |
The Information Retrieval (IR) 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 [45, 56]. 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 fine-tuned solely on our synthetic datasets outperform strong base-lines such as BM25 as well as recently proposed self-supervised dense retrieval methods.
