ELIPTZA : The Iptscrae Eliza

ELIPTZA is my Iptscrae version of the famous ELIZA; arguably the first "ChatBot" ever written. Originally intended to simulate a psychotherapy session, the bot responds to most statements by inverting the speaker's sentences and handing them back in the form of a question, asking you to elucidate or clarify your opinion. This approach, while occassionally annoying, does a pretty good job of keeping the conversation going for a while. Many people will talk with Eliptza for several minutes before they realize she is a bot.

ELIPTZA is a complex script, divided among multiple SPOTs. For this reason, the script is presented here as an entire Palace ROOM (with the default background "clouds.gif". To use the script, simply plug the entire room into your Pserver.pat file (making sure you don't use a room number that already exists in your Palace). You'll also have to provide your own graphic for Eliptza herself; to do this, make a new SPOT with the graphic of your choice, and move it into position so that her mouth is located in the middle of the room. Happy chatting!
