Original Abstract Submitted

A computer-implemented method for extracting data from printed documents comprises receiving a printed document and identifying the printed document as one of a structured form (including fully structured and semi-structured) and an unstructured form. Where the printed document is identified as a structured form, the method identifies first text features corresponding to keys for key-value pairs and identifies second text features that satisfy a proximity threshold (and optionally one or more key constraints) relative to the respective first text feature as the respective values of the respective key-value pairs, and records the values of the key-value pairs. Where the printed document is identified as a semi-structured form, the method may further comprise identifying at least one unstructured portion of the printed document and applying a trained machine learning model to the unstructured portion of the printed document to obtain additional values for additional key-value pairs.
