hi
actually i want to make a expert system in c or c++ how will i do that

[Curtis Rutland]

I thought you wanted to make an "expert system" in VB.NET?

Seriously, I have no idea what an "expert system" is.

Better add more information so that it will be easy for the people to help u.

Which expert system?
What do you want your expert system to be able to do?
Have you any ideas on how to design one and ultimately start coding one?
Did you ever programmed AI before?

Without more info we can't help you.

Every expert system needs to have it's knowledge base so it can build a knowledge tree out of it. For e.g,if you would describe him a animal(tiger perhaps) with sufficient data it would traverse the tree and find that animal if there is such a animal in tree.If there isn't it would need to ask you for the name of that animal and then store it in it's knowledge base.

But the problem is not every user will ask the question in same manner.Solution ?

Solution is keyword search.
E.g:

User might ask this question and expect to get tiger as answer:

"It's one of four big cats,has nice black vertical stripes,big fangs and claws....

Knowledge base will be made from if statements

IF mammal
  THEN IF big cat
    IF big claws AND big fangs
       THEN IF vertical stripes
          ANSWER Animal is a tiger.
       ELSE IF ASK Does it have mane?
          THEN ANSWER Animal is a lion.
    ELSE ...

ELSE ...

So you basically need to make your simple scripting language and then build a tree from it. Traversing the tree you will hopefully find the answer.Of course it's a good idea to make your keyword searching algorithm case-insensitive.

I hope this gave you some ideas.

I hope this gave you some ideas.

If you want to keep it that simple then you'd better turn it around: make the
computer ask questions that can be answered by the user by a simple yes
or no. That'd be the boolean value for the 'if' clauses and you don't need any
limited form of natural language parsing.

kind regards,
