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.

Dataset Creation

Source Data

Initial Data Collection and Normalization

Initial data was collected and processed by the authors of the research paper EDGAR-CORPUS: Billions of Tokens Make The World Go Round.

Who are the source language producers?

Public firms filing with the SEC.

Annotations

Annotation process

NA

Who are the annotators?

NA

Personal and Sensitive Information

The dataset contains public filings data from SEC.

Considerations for Using the Data

Social Impact of Dataset

Low to none.

Discussion of Biases

The dataset is about financial information of public companies and as such the tone and style of text is in line with financial literature.

Other Known Limitations

The dataset needs further cleaning for improved performance.

Additional Information
