+Buster is an Entity Recognition dataset consisting of 3779 manually annotated documents on financial transactions.
+Documents were selected using EDGAR (Electronic Data Gathering, Analysis, and Retrieval system) from the 
+U.S. Securities and Exchange Commission (SEC). 
+The corpus focuses on the main actors involved in business transactions. 
+Overall, there are three families of entities: Parties, Advisors and Generic information, for a total of 6 annotated
+entity types.
+We also released a corpus of 6196 automatically annotated documents.
