Abstract

A new method to recognize STEM contents in “e-born PDF,” which is produced originally from an electronic file such as a Microsoft-Word document, LaTeX system, etc., is developed. Character information (the character code, the font type and the coordinates on a page) extracted directly from a document is combined with analysis technologies in Math OCR. It improves recognition rate for STEM contents in e-born PDF remarkably, compared with ordinary image-based OCR approaches. This new method is actually implemented in our math OCR system (InftyReader).
