Automatic conversion of PDF-based, layout-oriented typesetting data to DAISY: potentials and limitations

Abstract

Only two percent of new books released in Germany are professionally edited for visually impaired people. However, more and more print publications are made available to the public in digital formats through online content delivery platforms like “libreka!”. The automatic conversion of such contents into DAISY would considerably increase the number of publications available in accessible formats. Still, most data available on “libreka!” is published as non-tagged PDF. In this paper, we examine the potential for automatic conversion of “libreka!”-based content into DAISY, while also analyzing the potentials and limitations of current conversion tools.
