| Abstract(in English) | In this paper, we built an on-line handwritten mathematical expression database for evaluation and training of mathematical expression recognition systems. We collected 1000 handwriting data of 200 mathematical expressions taken from scientific papers, and 20000 handwriting data of 245 mathematical symbols. We also explored a method to automatically estimate the alignment between input strokes and symbols. We could reduce labor in tagging alignment by hand using our previously proposed method for expression recognition under the grammatical constraint of the correct expression. |
