Systems and methods for domain agnostic document extraction with zero-shot task transfer

A system for performing document extraction, the system including a non-transitory computer-readable medium storing computer-executable instructions thereon such that when the instructions are executed, the system is configured to:

• receive a first document;
• extract the first document into document elements, the document elements including pages, lines, paragraphs, or any combination thereof;
• determine a first set of fields of interest for the first document, wherein the first set of fields of interest are determined via a type of the first document or via a first set of queries for probing the first document;
• determine, from a plurality of closed domain question answering (CDQA) models, a first set of CDQA models that provides answers to each field of interest included in the first set of fields of interest;
• and
• provide answers to the first set of fields of interest to the client device.
