【摘要】：数学公式格式转换是数学公式检索系统中的重要组成部分,而歧义公式转换的正确与否,会直接影响检索系统的查准率。实现歧义公式的转换,有利于为用户提供更准确的检索结果。数学公式检索中,为了给用户提供丰富的语义信息检索结果,提高检索的准确率,需要将LaTeX格式的数学公式转换为带有语义信息的Content MathML形式。针对转换过程中的歧义公式问题,提出了一种基于歧义运算符上下文的消歧方法。首先,根据歧义运算符映射表找到歧义运算符。其次,通过遍历数组提取歧义运算符的上下文内容。最后,依据歧义运算符上下文内容提取算法推断其具体含义。在类型系统方法的基础上,增加了对简单歧义数学公式转换的支持。实验结果表明,该方法在实际应用中能够有效解决La TeX数学公式到Content MathML转换过程中的歧义公式问题。
[Abstract]:The conversion of mathematical formula format is an important part of mathematical formula retrieval system. Whether the conversion of ambiguous formula is correct or not will directly affect the precision of retrieval system. In mathematical formula retrieval, in order to provide users with rich semantic information retrieval results, improve the accuracy of retrieval, It is necessary to convert the mathematical formula of LaTeX format into Content MathML form with semantic information. A disambiguation method based on ambiguous operator context is proposed to solve the ambiguity formula problem in the conversion process. Find ambiguous operators according to ambiguity operator mapping table. Secondly, extract the context content of ambiguous operator by traversal array. Finally, Based on the ambiguity operator context content extraction algorithm, the concrete meaning is inferred. Based on the type system method, the support for simple ambiguity mathematical formula conversion is added. The experimental results show that, This method can effectively solve the ambiguity formula problem in the conversion process of La TeX mathematical formula to Content MathML in practical application.
