An Approach to Similarity Search for Mathematical Expressions using MathML

Yokoi, Keisuke, Aizawa, Akiko

Similarity:

The recent global computerization and digitization trend has helped to increase the numbers of documents with mathematical expressions on the Web. These mathematical expressions have their own unique structures, and therefore, it is not an easy task for traditional search systems targeting natural languages to deal with them. We propose a similarity search method for mathematical equations that is particularly adapted to the tree structures expressed by MathML based on this background....

Ongoing Efforts to Generate “Tagged PDF” using pdfTeX

Moore, Ross

Similarity:

Recently PDF has been accepted as a standard for production of electronic documents, as ISO 32000-1:2008, with an acronym of PDF/UA (for “Universal Accessibility”). The second draft ISO 32000-2:2009 is to include specifications for including MathML tagging of mathematical environments and expressions. This talk presents a report on work-in-progress, aimed at: developing the primitive commands for pdfTeX needed to support the production of fully tagged PDF documents; writing appropriate...
