The University of Michigan maintains what we call “High Level Browse” — a mapping of LC/Dewey call numbers to a limited hierarchy, based loosely around academic departments (at least at the time it started). It’s still maintained, and may prove generally useful as well.
The HLB hierarchy <http://www.lib.umich.edu/browse> gives you an idea of what it is, and you can download and XML dump of the categories and their associated call number ranges <http://www.lib.umich.edu/browse/categories/xml.php> (1.8mb) if that’s your thing.
