Mathematical Document Classification via Symbol Frequency Analysis

Watt, Stephen M. (2008)

Towards Digital Mathematics Library. Birmingham, United Kingdom, July 27th, 2008

Earlier work has examined the frequency of symbol and expression use in mathematical documents for various purposes including mathematical handwriting recognition and forming the most natural output from computer algebra systems. This work has found, unsurprisingly, that the particulars of symbol and expression vary from area to area and, in particular, between different top-level subjects of the 2000 Mathematical Subject Classification. If the area of mathematics is known in advance, then an area-specific...

Mathematical Formulae Recognition

Průša, Daniel, Hlaváč, Václav (2008)

Towards Digital Mathematics Library. Birmingham, United Kingdom, July 27th, 2008

We present a summary of our work in progress related to mathematical formulae recognition. Our approach is based on the structural construction paradigm and two-dimensional grammars. It is a general framework and can be successfully used in the analysis of images containing objects exhibiting rich structural relations. In contrast to most of all other known approaches, the method does not treat symbols segmentation and structural analysis as two separate processes. This allows the system to solve...

MathML-aware Article Conversion from LaTeX

Stamerjohanns, Heinrich, Ginev, Deyan, David, Catalin, Misev, Dimitar, Zamdzhiev, Vladimir, Kohlhase, Michael (2009)

Towards a Digital Mathematics Library. Grand Bend, Ontario, Canada, July 8-9th, 2009

Publishing in Mathematics and theoretical areas in Computer Science and Physics has been predominantly using TeX/LaTeX as a formatting language in the last two decades. This large corpus of born-digital material is both a boon — LaTeX is semi-semantic format where the source often contains indications of the author’s intentions — and a problem — TeX is Turing-complete and authors use this freedom to use thousands of styles and millions of user macros. Several tools have been developed to convert...
