We release the raw passages, embeddings, and index of MassiveDS.
Website: https://retrievalscaling.github.io
Versions
We release two versions of MassiveDS:
- MassiveDS-1.4T, which contains the embeddings and passages of the 1.4T-token datastore.
- MassiveDS-1.4T-raw-text, contains the raw text of the 1.4T-token datastore.
- MassiveDS-140B, which contains the index, embeddings, passages, and raw text of a subsampled version containing 140B tokens in the datastore.
Note:
- Code support to run with MassiveDS is in https://github.com/RulinShao/retrieval-scaling.
File structure
raw_data: plain data in JSONL files.passages: chunked raw passages with passage IDs. Each passage is chunked to have no more than 256 words.embeddings: embeddings of the passages encoded with Contriever-MSMACRO.index: flat index built with embeddings.
Download
We recommend using Git LFS to download large files. We provide an example script below.
First, clone the Git history only to start working with it.
git clone --filter=blob:none https://huggingface.co/datasets/rulins/MassiveDS-1.4T
cd MassiveDS-1.4T/
(Optionally) Specify the directory that you want to partially download, e.g., the embeddings only. Skip this step if you want to download everything.
git sparse-checkout init --cone
git sparse-checkout set embeddings
Finally, pull the data.
git lfs install
git lfs pull
