The Hoberg and Phillips firm-scope database, along with its industry mappings, is based on the text firms use to describe their businesses and product offerings in annual public-firm 10-K disclosures. Scope is identified at the individual firm level using doc2vec and k-means spatial models that reduce the dimensionality of product descriptions and group their content into buckets based on common product discussions. Keywords that most define each unique industry are then used to map firms to the industries they serve and thus compute scope as the count of the industries a given firm serves in a given year.

The scope database is best described through its two parts (two separate potential downloads). The first is a firm-year panel database containing information about each firmís scope.The second is a higher dimensional mapping database that indicates the specific doc2vec industries each firm likely operates in within each year. The result is a firm-industry-year panel database with textual scores indicating how strong the link is between each firm and its mapped industries.
