Not really an application for a home PC (although I suppose you could
cram it in), but you might be interested in the smarts developed by Andrew
Taylor (andrewt at cse.unsw.edu.au, http://www.cse.unsw.edu.au/~andrewt/)
at the University of NSW.
Andrew, a computer science engineer rather than a botanist, took some
English language botanical descriptions (Eucalyptus and Angophora from
the Flora of Australia), minced them through some clever natural
language processing algorithms, and reversed engineered a more or less
recognizable DELTA dataset.
He made the dataset queryable on the WWW with clients/browsers with
forms cabability (Mosaic, Netscape, etc.) both as a set of independent
menus and a set of check boxes.
Using some nifty lateral thinking, he figured one could use the same
algorithm to parse an arbitrary description of a plant, and then match
the result of this description against the already parsed dataset. The
result is a dialog box in which you write a natural language description
of the plant and let the server find the best matches for you.
It may not be bomb-proof, but it is a bloody clever and interesting
You can find this application on:
This is research in progress at a computer engineering school, and the
server is often under a lot of strain and not available, but it is worth
having a look at the outline and the interfaces.
