ELIZA—a computer program for the study of natural language communication between man and machine
A starting point for understanding how a conversation can feel meaningful even when the underlying system follows relatively simple rules.
What it contributes
Describes ELIZA's pattern-based processing and response generation. It offers a concrete early example of a conversational interface whose apparent conversational ability exceeds the sophistication of its mechanism.
Read with care
This is a historical system description, not an evaluation of modern language models or evidence about the long-term effects of AI companionship.
Why it belongs here
Read it to separate the mechanism producing a response from the meaning a person may bring to it.
