| Abstract(in English) | We are building a QA system about scientific literatures. We can ask questions such as ``what is the definition of C-value?''Its answer is a mathematical formula. Thus, mathematical formulas play important roles just like named entities in Open Domain Question Answering. %We are not interested in how the formula is constructedUnlike Math OCR, we are not interested in how the formula is constructedand simply treat formulas as images. In this paper, we present a formula image detection method based on Deep Learning and open source OCR software. First, we tried Deep Learning to detect mathematical formulas, but it was difficult to detect in-line formulas. Therefore, we also used open source OCR software. We show experimental results based on ACL Anthology papers. |
