PARRY is, besides ELIZA, the other famous early chatterbot. PARRY was written in 1972 by psychiatrist Kenneth Colby, then at Stanford University. While ELIZA was a tongue-in-cheek simulation of a Rogerian therapist, PARRY attempted to simulate a paranoidschizophrenic. 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. Example of ELIZA in Emacs. ... A chatterbot is a computer program designed to simulate an intelligent conversation with one or more human users via auditory or textual methods. ... Stanford redirects here. ...

Milman Parry (1902 -December 3, 1935) was a scholar of epic poetry.
In his American publications of the 1930s Parry introduced the hypothesis that this peculiarity of Homer's style is to be explained by its being the characteristic style of oral composition (the so-called Oral Formulaic Hypothesis).
Between 1933 and 1935 Parry, at the time Associate Professor at Harvard University, made two trips to Yugoslavia, where he studied and recorded oral traditional poetry of the South Slavs.
