Abstract: The paper introduces the recognizing and extracting methods of mathematics expressions in formula-based mathematics search engine.Itsummarizes the corresponding features of MathML,OpenMath,LaTex and Infix when they are embedded in a Web page.A feature-based heuristic method of recognizing and extracting mathematical expressions is given in the paper.The experimentsproves that the method is effective and useful.

Key words: search engine, crawler, formulas search, mathematical formulas, MathML, OpenMath
