Practice Report: A Conversion Tool for Mathematical Expressions in Web XML Files
Since Practice Reports do not have abstracts, we have provided an extract of the beginning of the full text.
HTML (Hypertext Markup Language) is the set of “markup” tags that codes computer files for display on the World Wide Web. These tags or codes tells the user';s browser program how to display a web page';s text and images. Although HTML has a large repertoire of tags and is the best-known web-description language, it has no tags to describe mathematical expressions. With no means of using HTML tags to mark up mathematical expressions, authors have resorted to crude solutions. One popular method involves inserting images—literally, snapshots of equations taken from other programs and saved as image data files, such as in GIF (Graphics Interchange Format)—into technical documents that have a mathematical or scientific content. No screen reader is able to recognize these image data, and people who are visually impaired (that is, are blind or have low vision) cannot understand the mathematical expressions. There are numerous pictures and animations on web pages, but visually impaired people cannot understand this colorful and active information.
