Using WRDS to connect RavenPack data with Compustat data
Linking RavenPack with Compustat (NA)
RavenPack (/wrds/ravenpack/sasdata/) is a database that extracts information on named entities with sentiment, and financially-relevant events from the unstructured content of thousands of publications. In WRDS, RavenPack contains a file named WRDS_COMPANY_NAMES (/wrds/ravenpack/sasdata/common) that contains the identifiers ( RP_ENTITY_ID, ISIN, CUSIP, and TICKER). Ravenpack’s CUSIP (9-character cusip) could be used to link with Compustat’s CUSIP (9-character cusip).
This sample code shows the procedure. Please make sure to select "SAS" in the kernel list when trying to run the code in Jupyter Notebook environment.

Linking RavenPack with Compustat Global
To link RavenPack data with Compustat Global data, begin by using the RavenPack WRDS_COMPANY_NAMES file as shown in the instructions above. Then, merge the WRDS_COMPANY_NAMES with the Compustat Global data by using the ISIN. The following sample code shows the procedure for linking the identifiers of both databases:
