In this paper we propose a method for correcting character recognition errors at the higher level recognition step of the mathematical formulae recognition and understanding system.
The system consists of two-level recognition steps: the low level recognition including character recognition, and the higher level recognition including layout recognition.
We apply the layout information recognized in the latter step, and character recognition errors are corrected by using two sources of information.
One is by some keywords such as mathematical function names, and the other is based on a cost tree and co-occurrence probabilities between symbols.
Availability of the proposed method is indicated by some experimental results, and the character recognition rate raised from $79.8\%$ to $90.2$\% and the formula recognition rate raised from $5.8\%$ to $41.1\%$ are confirmed. |
