Samuel --
I'd like to call your attention again to
We are close to a base release (probably this week) of a 44,000 word English
word database that has a very rich array of information helpful to the
teaching of English, especially reading.  A 10,000 word Spanish lexicon and
50000 word German one will follow. Norbert Rennert who compiled these, would
like very much to work with other language experts to extend this effort to
other languages.  Some highlights of the English lexicon:  screened from the
CMU Sphynx corpus for accessibility to children, each word entry has
frequency data from analysis with respect to a large corpus of text merged
in, phoneme breakdown (used by reading curricula to decide the order in
which words should be introduced or deemed decodable), etymology, semantic
domain (categorization), IPA coding, syllabification and stress marking.

The second release will merge in many images, though we don't expect to have
a complete image-to-word mapping without a volunteer effort.   We plan to
create an API and a way to define a curriculum sequence for word groups once
the basic database is released, to allow integration of the word bank across
all the activities that are literacy related, as well as create more.  We
also hope to use the word bank to score texts for reading level and assist
in creation of simplified version of extant texts suitable for use by
emergent readers.  Please read our design documents at the above site.
