PARRY

From Wikipedia, the free encyclopedia

PARRY is, besides ELIZA, the other famous early chatterbot. PARRY was written in 1972 by psychiatrist Kenneth Colby, then at Stanford University.^[1] While ELIZA was a tongue-in-cheek simulation of a Rogerian therapist, PARRY attempted to simulate a paranoid schizophrenic.^[1] The program implemented a crude model of the behavior of a paranoid schizophrenic based on concepts, conceptualizations, and beliefs (judgements about conceptualizations: accept, reject, neutral). It also embodied a conversational strategy, and as such was a much more serious and advanced program than ELIZA.

PARRY and ELIZA (also known as "the Doctor"^[2]^[3]) "met" several times.^[1]^{RFC 439}^[2] The most famous of these exchanges occurred at the ICCC 1972, where PARRY and ELIZA were hooked up over ARPANET and "talked" to each other.^[2]
