Huifang Guo, Xuedong Tian, Fang Ou Yang, Xinfu Li · 2011
Towards the needs of retrieving mathematical formulas, this paper details the semantic descriptors of MathML by utilizing the extensibility of XML and the characteristics of mathematical formulas through the analysis of the existing mathematical formula marking languages. We define a description attribute on the basis of MathML for conversion and retrieval of mathematical formulas in various formats, and also realize the conversion between the extended MathML and LaTeX. Experiments show that this method can strengthen the capability to describe the semantic information of formulas and improve the precision and efficiency of conversion and retrieval of mathematical formulas.
