摘要：

This paper presents clustering of online handwritten mathematical expressions (HMEs) to help human markers to mark them efficiently and reliably. We propose bag-of-features from online handwritten mathematical expressions. It consists of 6 levels of features from low-level pattern features to high-level symbolic and structural features which are obtained from recognizing online HMEs. Experiments are conducted on our dataset. The best clustering result is 0.9185 for purity, which is obtained by applying the combination of both low-level and high-level features with the k-means++ algorithm.
