[comp.ai] req. for knowl. reason. tools for NL Text Understanding

geertp@kunivv1.sci.kun.nl (Geert Postma) (03/22/90)

Because an earlier direct posting to the comp.ai.nlang-know-rep group did
not appear and within the comp.ai.shells group hardly any useful reply was
received I would like to post within this group the next three questions:

First:
        Are there people who have developed a network (or 
        frame-based) Reasoning System, preferably programmed in Prolog 
        (and preferebly NU- or MU-Prolog), for the development of
        a Natural Language Text Understanding System? And are they
        willing to share or sell the program? Or does anyone know
	addresses of people/companies that sell this kind of
	programs for the mentioned purpose?
	I already know of BACK, FLEX and RHET.

Second:
	Of the network based system KNET (Prolog based; Freeman, Hirschman 
	et.al.), Krypron or NILK (Brachman, Moser) I don't have an address.
	Can someone provide more information?

Third:
        Are there people who have some experience with KEE for the
        development of a Natural Language Text Understanding System?
        I am interested in possible problems concerning e.g. the 
        representation of the 'world knowledge'. References to 
        articles are of course welcome too.

Thanks in advance,

Geert J Postma
