What core technique did ELIZA primarily use for developing its conversational scripts?
Answer
Pattern matching and substitution
ELIZA's operational core relied entirely on pattern matching and substitution techniques to formulate responses. This involved identifying specific keywords or sentence structures in the user's input and applying a pre-written transformation rule to generate a seemingly relevant output. For instance, recognizing 'I am feeling...' allowed the system to trigger a template response like 'How long have you been feeling sad?', demonstrating syntactic manipulation rather than semantic understanding.
