BinProlog 9.00 (just released - see


    http://www.binnetcorp.com )


compiles to C, has a simplified, easy to modifiy/adapt WAM and
can be licensed in source form.


Both products provide extensive support for advanced natural language
processing (see:


    http://www.cs.unt.edu/~tarau/research/researchPapers.html )


We also provide a fast Java based Prolog implementation - Jinni 2002 -
(source licensing included) - and 3 completely free, open sourced
Prolog implementations (see


http://www.binnetcorp.com/OpenCode )


two of them in Java and one in C - containing older versions of
our commercial products.


As implementing a viable Prolog system can become easily a 3-5
person/year project, I would recommend starting with one of
the above - and adapt/customize it for your specific needs.
