摘要 简要回顾了数学公式结构分析的发展,指出数学公式结构分析针对各种数学公式的复杂结构,攫取出公式的版面结构和语义信息.因此,本文提出了一个在语法结构分析指导下的版面结构分析方法,给出了其系统架构,对系统中用到的版面结构分析方法进行了优化,并给出了最终实验结果. The development of structure analysis of mathematical expression was reviewed briefly. Structure analysis analyzes the complicated structures of mathematical expressions, and snatches their layout structure and logic meaning. In this paper, a method of layout analysis under the instruction of syntactic analysis and the system built on it are presented. The methods are optimized, and the results of experiments are given.
