Bag of Words
Researchers can use this WRDS SEC text Analysis tool to query word counts across all SEC filings, or against specific company filings. The tool includes a Word Summary query form, presenting the stem and lemma of the queried word along with word attributes, such as whether the word is positive or negative, geographic, a company name, or patent-related (with KtMINE subscription).
