Dataset Card for [EDGAR-CORPUS]

Dataset Summary

This dataset card is based on the paper EDGAR-CORPUS: Billions of Tokens Make The World Go Round authored by Lefteris Loukas et.al, as published in the ECONLP 2021 workshop.

This dataset contains the annual reports of public companies from 1993-2020 from SEC EDGAR filings.

There is supported functionality to load a specific year.

Care: since this is a corpus dataset, different train/val/test splits do not have any special meaning. It's the default HF card format to have train/val/test splits.

If you wish to load specific year(s) of specific companies, you probably want to use the open-source software which generated this dataset, EDGAR-CRAWLER: https://github.com/nlpaueb/edgar-crawler.
