Abstract

This paper describes an online recognition system based on a pen-based interface that can be used to analyse the structure of mathematical expressions. Some of the topics include a feature-based spatial analysis technique and a procedure for constructing expressions based on relationship precedence. The algorithm discussed combines symbol recognition, spatial analysis and parsing techniques, to generate an expression tree of the given mathematical expression.
