[Under Construction]

This is a repository containing all the queries from the Japanese part of the MMarco dataset, the multilingual version of the MSMarco dataset.

For each query, there are matching hard negatives:
- 25 of them retrieved by the multilingual e5 base model.
- Up to 10 of them retrieved by the basic implementation of BM25 from Japanese in the Anserini library.
