Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes installation of a mathematical formula recognition module into open source OCR system OCRopus, especially we consider the identification of inline formulas. Splitting a textline which includes math formulas into words and verifying them using a language model, we can distinguish the math formulas from words. Additionally, because the math formulas tend to have a variety of bounding boxes of symbols aspect ratios, we employ SVM using features associated with the bounding boxes so as to improve the accuracy of identification.
