2. Who is Eliza?
Computer program developed in 1966 by Joseph Weizenbaum (* 8. Jannuary 1923, † 5. March 2008).
Very early example of natural language processing.
One of the first chatterbots in existence.
Named after Eliza Doolittle, a character in George Bernard Shaw’s Play Pygmalion.

3. Who is Eliza? The program can simulate a human-like interaction.
Its mission was the attempt to replicate the conversation between a psychoanalyst and a patient. In a therapeutic situation a human being can reply to a statement with a question, that indicates very little specific knowledge of the topic.

4. Basically ELIZA works by turning everything you say around:
How does it work?
Basically ELIZA works by turning everything you say around:
Input text is read and inspected for keywords,
sentence is transformed according to a rule associated with the keyword,
if no keyword is found, a content-free remark is retrieved.
More complex:
Keywords may have a rank; identification of the most important keyword.
Identification of some minimal context within which the chosen keyword appears.
Choice of an appropriate transformation rule + making of the transformation.
Respond “intelligently” even if no keyword is detected in the input text.

5. Demo
Various versions available for download or to use online i.E.
