Efficient document information extraction system using optical character recognition (ocr) information

A system, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive optical character recognition (OCR) information of a document, wherein the OCR information corresponds to one or more word boxes;
• determine beginning, inside, and outside (BIO) tags and labels of the one or more word boxes based on the OCR information;
• group a first word box and a second word box based on BIO tags of the first and the second word boxes;
• merge the first and the second word boxes into a combined word box based on a label of the first word box matching a label of the second word box;
• and
• output the combined word box and the label of the first word box.

A non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations to extract document information, the operations comprising:

• receiving optical character recognition (OCR) information of a document, wherein the OCR information corresponds to one or more word boxes;
• determining beginning, inside, and outside (BIO) tags and labels of the one or more word boxes based on the OCR information;
• grouping a first word box and a second word box based on BIO tags of the first and the second word boxes;
• merging the first and the second word boxes into a combined word box based on a label of the first word box matching a label of the second word box;
• and
• outputting the combined word box and the label of the first word box.
