توضیحات :
The dialogue above is from ELIZA, an early natural language processing system
that could carry on a limited conversation with a user by imitating the responses of
a Rogerian psychotherapist (Weizenbaum, 1966). ELIZA is a surprisingly simple
program that uses pattern matching to recognize phrases like “I need X” and translate
them into suitable outputs like “What would it mean to you if you got X?”. This
simple technique succeeds in this domain because ELIZA doesn’t actually need to
know anything to mimic a Rogerian psychotherapist. As Weizenbaum notes, this is
one of the few dialogue genres where listeners can act as if they know nothing of the
world. Eliza’s mimicry of human conversation was remarkably successful: many
people who interacted with ELIZA came to believe that it really understood them
and their problems, many continued to believe in ELIZA’s abilities even after the
program’s operation was explained to them (Weizenbaum, 1976), and even today
chatbots such chatbots are a fun diversion
