Functional programming practice (Scheme)
ELIZA (Doctor) is a classic example of the use of Lisp in a sample artificial intelligence (AI) application. Originally written by Joseph Weizenbaum, ELIZA is a program that "simulates" a patient's discussion with a psychiatrist. While appearing on the surface to possess "intelligence", the program is actually little more than a simple pattern matcher. A sample dialogue with ELIZA follows (user input is in lower case, with ELIZA's responses in upper case):
- MAY I HELP YOU?
- i want you to help me
- WHAT WOULD IT MEAN TO YOU IF YOU GOT ME TO HELP YOU?
- im afraid to tell you
- YOURE NOT REALLY TALKING ABOUT ME, ARE YOU?
- what does that mean
- WHY DO YOU ASK?
- are you asking me
- WHY ARE YOU INTERESTED IN WHETHER OR NOT I AM ASKING YOU?
- why do you keep answering with questions
- DOES THAT QUESTION INTEREST YOU?
- i dont know
- DONT YOU REALLY KNOW?
- no
- ARE YOU SAYING NO JUST TO BE NEGATIVE?
- i think so
- DO YOU REALLY THINK SO?
- not always
- CAN YOU THINK OF A SPECIFIC EXAMPLE?
- oh shut up
- IM NOT SURE I UNDERSTAND YOU FULLY?
- goodbye
- GOODBYE
