Abstract

Mathematical OCR (Optical Character Recognition) systems retrieve character sequences and the structure of mathematical formulae from raster images scanned from mathematical documents. In this paper a method for detecting hyperlinks, e.g. formula links, from mathematical OCR output is described. We also experimentally demonstrated the effectiveness of the method. By using the method we implemented a prototype system of a mathematical knowledge browser that helps people read mathematical articles.
