Thank you so much.

Dear Thomas.
Now I want to make Labview call Prolog,but I can't find any material.Did you ever have experience with this?

Wow,Thomas,you are a genius.Thank you :D :D The "DCG" is perfectly solved beyond my expectation. And I have tested the ";" again.There is a problem here.When I define such a predicate: class predicates fact:(integer N, integer Res) procedure (i,o). clauses fact(N, F) :- (N<=1,F=1...

Dear friends: In swi-prolog I can do such thing "sentence --> nounphrase, verbphrase." The "-->" which is called DCG(Definite Clasue Grammer). and in swi-prolog I can take ";" as "if else" to use. Whether can visual prolog do things like above? :D :D :D

For a real domain you will have to include "digits" in the definition like this: domains limited = [0..50] digits 16. (16 is actually the only sensible choice). You cannot define a sub-set of string like you propose, but you can define a functor domain with a fixed set of functors/enumera...

Visual Prolog does not have facilities for making calls in that way, you will have to create an interpreting predicate yourself: class predicates interpret : (string List). clauses interpret(["forward", LenStr, Unit]) :- Len = tryToTerm(integer, LenStr), !, forward(Len Unit). ... interpre...

Well, I see that what you mean by "natural language processing" is at a starting level. I think then you should deal with the problem with some method : 1) you can get answers to such questions in the book Visual Prolog for Tyros which will gradualy show you how VIP works. 1) you should l...

Hi, Natural language processing is a world of its own. There is a priori no reason to think that a computer language is better than another to do such a thing. But a main feature of that world is that it requires many original modelling tools. The advantadge of VIP is that it's very well adapted to...

If it is able to do such things,can you recommend some books,articles,tutorial,whatever,etc.Thank you very much.
