Presenting Mathematical Expression Images on Web to Support Mathematics Understanding
People cannot use a text search to find mathematical expressions because expressions cannot be replaced with words. Our research uses an ordinary text search and presents appropriate mathematical expression images (hereinafter called math-images) for input keywords. First we classify a set of the top ranking images from all the images in HTML files by scoring them. We focus on three viewpoints that are unique to mathematical expression images and mark the images by using these viewpoints. Then by adding bonus points to these marked images, the best three images are chosen from the set and presented with an explanation of the keyword and the surrounding information in the HTML files. We conducted two experiments to optimize the parameters of the expression giving the mark and to evaluate the effect of the bonus points. The rate of the average correct images of the best three was 79.5%.
