Document extraction template induction

A system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• receiving, from a user device associated with a user, an annotated document, the annotated document comprising one or more fields, each respective field of the one or more fields of the annotated document labeled by a respective annotation;
• determining, using a template matching algorithm that evaluates non-value text and structural layout features of documents, that the annotated document fails to satisfy a similarity threshold with each cluster in a set of clusters;
• based on determining that the annotated document fails to satisfy the similarity threshold, clustering, using the template matching algorithm, the annotated document into a new cluster of the set of clusters;
• inducing, using the annotated document assigned to the new cluster, a document template for the new cluster, the document template defining expected spatial locations of the one or more fields relative to non-value text and structural layout features of the annotated document;
• receiving, from the user device, an unannotated document comprising the one or more fields;
• clustering, using the template matching algorithm, the unannotated document into the new cluster;
• and
• in response to clustering the unannotated document into the new cluster, extracting, using the document template, the one or more fields by applying the defined expected spatial locations of the one or more fields from the document template to the unannotated document to identify and retrieve content from corresponding regions.
