Content MathML(CMML) conversion using LATEX Math Grammar (LMG)

Abstract Syntax Tree (AST) is one of the main requirements to extract semantic information from a mathematical expression given in LATEX format and to make it machine readable for its interoperability in heterogeneous environments. In this paper, a grammar-based algorithm is proposed that converts LATEX math expression into Content MathML (CMML) to produce semantic enrichment in web documents. Initially, the conversion algorithm is tested on 20 equations used in NTCIR-12 math competition, later the algorithm is tested on NTCIR-12 Wikipedia-MathIR data-set. The results show that our algorithm is capable of converting LATEX complex equations into CMML extensively as compared to the existing ones.
