Researchers have introduced LakeQuest, a new benchmark designed to evaluate question-answering systems on realistic data lakes. This benchmark comprises 9,846 human-validated QA pairs across three domains: AI/ML metadata, retail banking, and biomedical information. Initial evaluations using retrieval-augmented generation (RAG) and agentic tool-use methods revealed significant challenges for current systems in areas like relation chaining, policy grounding, and joint tabular QA, indicating a need for improved discovery and composition mechanisms.
