Document Type and Number:
WIPO Patent Application WO/2023/075434
Kind Code:
A1
Abstract:
The present invention relates to a machine learning-based digital reference book provision system using bounding boxes. The machine learning-based digital reference book provision system using bounding boxes according to the present invention comprises a digital conversion server. The digital conversion server comprises: an area detection unit that detects problem areas in a portable document format (PDF) file of a digital reference book, and divides the problem area into a question area and an answer area by detecting the answer area in the problem area; and an element extraction unit that extracts elements from the question area and the answer area, and saves the extracted elements to a database unit, wherein the area detection unit detects, as the answer area, an area in the question area in which a circled number is detected.
