摘要/Abstract

摘要： 本文主要研究基于公式的数学搜索引擎中数学公式的识别和提取方法,总结了MathML、OpenMath、LaTex、Infix格式数学公式在网页中出现时的各自特征,提出了基于特征和启发式规则的公式识别和提取方法,并用实验说明了该识别和提取方法的可行性和准确率。

关键词: 搜索引擎, 爬虫, 公式搜索, 数学公式, MathML, OpenMath

Abstract: The paper introduces the recognizing and extracting methods of mathematics expressions in formula-based mathematics search engine.Itsummarizes the corresponding features of MathML,OpenMath,LaTex and Infix when they are embedded in a Web page.A feature-based heuristic method of recognizing and extracting mathematical expressions is given in the paper.The experimentsproves that the method is effective and useful.

Key words: search engine, crawler, formulas search, mathematical formulas, MathML, OpenMath
