I am currently evaluating available lexicons as part of a project to develop a NLP system with commercial potential. I would like information concerning machine-readable lexicons and thesauri that are not now commercial products but that are publically or privately available. Specifically, I am interested in the following information: (1) number of words and how they were selected for inclusion in the lexicon, (2) how much and what kind of syntactical information is incorporated, (3) for verbs, whether case information is included, and if so, what kind and to what extent, (4) whether the lexicon incorporates any class hierarchy information, (5) references to research using the lexicon, (6) the willingness of the owner to share or sell, and approximate price if for sale, (7) other descriptive information necessary for evaluating the contents of the lexicon. Please reply directly to: Weber3%Harvarda.BITNET@WISCVM.WISC.EDU Thanks in advance. If the replies are sufficiently interesting, I will repost.

Although you mentioned that you are not intrested in commericial lexicons,
I would suggest you contact someone in AI R&D at Wang Laboratories. I
spent several years there working on these and can assure you that they are
quality lexicons containing all (and more) of the information you require.
The source of data is the Random House Unabridged Dictionary, to which
they own exclusive computer rights. They also have on-line lexicons dealing
with Legal Terms, Medical Terms, Scientific Terms, Roget's Thesaurus,
Place-Names, Translation Aids to French, German, Spanish, Italian, Japanese,
Chinese, Korean, and Arabic, British Spellings of words,
and other specialized lists. It is quite possible that Wang
might let you use their information in return for application and
consultation access. Send me mail if you would like to persue this, and
need specific contacts there.
