KILT: Benchmarking Knowledge Intensive Language Tasks for Grounded Generation
Developed the KILT benchmark standardizing evaluation across open-domain QA, fact checking, entity linking, and dialogue, measuring both answer generation accuracy and provenance attribution.
Corpus snapshot drift requires periodic index refreshes to keep knowledge-intensive models updated with real-world facts.
Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks
Authored the foundational NeurIPS 2020 paper defining Retrieval-Augmented Generation (RAG), introducing end-to-end differentiable architectures that ground generative models against external non-parametric neural indices.
Early RAG formulated single-step retrieval; complex multi-hop reasoning requires iterative or agentic retrieval loops.
