Automatically Rearranging Structured Data for Customised Special-Needs Presentations

Computers are most frequently used for processing text, or for processing signalbased data such as graphics, audio and video. However, there is also a significant amount of non-textual symbol-based data, such as musical scores, mathematics, schematics, and scientific models, that are encoded in such a way that they can be manipulated by algorithms at a higher level than simply processing the signal. Such data can be used for complex search queries, for example.
