Web Framework for Evaluating Handwritten Math Expression Recognition

In this paper we present a new web framework for compiling and publishing evaluation results for CROHME 2016. The framework makes user easier to view and organize handwritten math expression recognition evaluation results produced by the LgEval library. LgEval is used for evaluating structural pattern recognition systems, which was originally developed as the standard evaluation tool for the CROHME competition. It consist of a set of command line tools running with bash for evaluating, visualizing and translating label graphs. The library could also be used to represent and evaluate structure for other problems which could be reduced to label graph format. The web framework integrates LgEval as a core module, and executes corresponding functions when user submit the math expression pattern recognition result to the server. Our system reaches the goal of transparency and accuracy. Keywords-handwritten math recognition; evaluation system; label graph; web framework
