The ROOTS corpus was developed during the [BigScience workshop](/static-proxy?url=https%3A%2F%2Fbigscience.huggingface.co%2F) for the purpose
of training the Multilingual Large Language Model [BLOOM](https://huggingface.co/bigscience/bloom). This tool allows
you to search through the ROOTS corpus. We serve a BM25 index for each language or group of languages included in
ROOTS. You can read more about the details of the tool design
[here](https://huggingface.co/spaces/bigscience-data/scisearch/blob/main/roots_search_tool_specs.pdf). For more
