  I had difficulty understanding your first paragraph. I tried to fix the punctuation. So I searched the inernet and found http://books.google.com/books?id=y3kaQxIns0oC&printsec=frontcover Portions of your first paragraph match what is in page 50 in that book. I also found http://hestia.typepad.com/flatlander/2010/07/f-pattern-matching-for-beginners-part-1-getting-started.html Portions of your first paragraph match what is in that article. So I used those to help me determine what you meant to say in your first paragraph and I apologize if I got it wrong.

    Everyone takes help for learning if one doesn't know about the new technology.so concept or the exact definition can be same because the definition we can't change which is predefined.Have you faced any problem with this ? one thing more sam if you will search articles you will find some things common from books or other sources and I apologies if I said anything wrong.

    You are right sam pattern matching is different where as pattern recognition is some thing else here we are discussed only about pattern matching which is in F# not about Pattern recognition that's a part of Artificial Intelligence.

  How does pattern matching in F# compare to regular expressions? Is F# patterns anything like Backus–Naur Form (BNF)? I think it would be very interesting to know how F# patterns compare to those used in the "String Oriented Symbolic Language" SNOBOL of fifty years ago. For the benefit of others, note that there is a difference between Pattern Matching and Pattern Recognition. Pattern Recognition is an Artificial Intelligence thing and can be very complex.
