The aim of this paper is mainly to analyze the problem on post-processing techniques of mathematical formula structural analysis. First, analyzing the errors in the results of the formula structural analysis and finding the causes of the mistakes caused by analyzing module. Then, concluding and summarizing these errors by using the knowledge of grammatical and semantic, making rules according the analysis result. At last, traversing and checking the syntax tree generated by structural module to find the errors existing in it and make corresponding modifies with the rules of grammatical and semantic. The result of experiments shows that the method proposed in this paper can achieve higher accuracy as well as better application efficiency. |
