MS MARCO v2.1 QA (Lance Format) A Lance-formatted version of MS MARCO v2.1 — Microsoft's machine-reading-comprehension benchmark built from anonymized Bing query logs. Each row is one user query, the up-to-10 candidate passages Bing retrieved for it with relevance flags, and the human-written reference answers, with MiniLM query embeddings stored inline and pre-built ANN/FTS indices, available directly from the Hub at hf://datasets/lance-format/ms-marco-v2.1-lance/data.… See the full description on the dataset page: https://huggingface.co/datasets/lance-format/ms-marco-v2.1-lance.
