【摘要】：數(shù)學(xué)公式格式轉(zhuǎn)換是數(shù)學(xué)公式檢索系統(tǒng)中的重要組成部分,而歧義公式轉(zhuǎn)換的正確與否,會直接影響檢索系統(tǒng)的查準(zhǔn)率。實(shí)現(xiàn)歧義公式的轉(zhuǎn)換,有利于為用戶提供更準(zhǔn)確的檢索結(jié)果。數(shù)學(xué)公式檢索中,為了給用戶提供豐富的語義信息檢索結(jié)果,提高檢索的準(zhǔn)確率,需要將LaTeX格式的數(shù)學(xué)公式轉(zhuǎn)換為帶有語義信息的Content MathML形式。針對轉(zhuǎn)換過程中的歧義公式問題,提出了一種基于歧義運(yùn)算符上下文的消歧方法。首先,根據(jù)歧義運(yùn)算符映射表找到歧義運(yùn)算符。其次,通過遍歷數(shù)組提取歧義運(yùn)算符的上下文內(nèi)容。最后,依據(jù)歧義運(yùn)算符上下文內(nèi)容提取算法推斷其具體含義。在類型系統(tǒng)方法的基礎(chǔ)上,增加了對簡單歧義數(shù)學(xué)公式轉(zhuǎn)換的支持。實(shí)驗(yàn)結(jié)果表明,該方法在實(shí)際應(yīng)用中能夠有效解決La TeX數(shù)學(xué)公式到Content MathML轉(zhuǎn)換過程中的歧義公式問題。
[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.
