| Abstract(in English) | We propose a new method for evaluating the performance of on-line handwritten mathematical formula recognition systems. The proposed method uses the number of interactive "error correction" operations required according to incorrect recognition of handwritings. When we input mathematical formulas into a computer using on-line handwriting recognition systems, errors may occur in three stages : (1) symbol segmentation, (2) symbol recognition, and (3) mathematical structure recognition. In general, it is not so simple to evaluate the performance of whole recognition system since the errors often depend on each other. In this paper, we present an intuitive and quantitative method for evaluating the whole recognition system by measuring the number of "error correction" operations to obtain correct formulas interactively based on incorrect recognition results. |
