Image reading systems, methods and storage medium for performing geometric extraction

A method for processing a document having one or more pages, comprising:

• receiving an unstructured document at a document receiving device;
• generating an initial graph representation of at least a portion of the unstructured document, the initial graph representation including textual blocks, bounding boxes surrounding the textual blocks, and search paths connecting the bounding boxes;
• generating a confidence level score for the initial graph representation based on geometric characteristics of the textual blocks and bounding boxes;
• reviewing the generated graph representation to identify errors based on subject matter context of the unstructured document;
• when an error is identified, regenerating the graph representation by recognizing textual blocks on the at least a portion of the unstructured document, generating bounding boxes for the recognized textual blocks, determining search paths connecting the generated bounding boxes, and generating a regenerated graph representation;
• and
• the process continuing for multiple iterations until the confidence level score is above a threshold confidence level score.
