To do this I set up a feedback loop, or freestyle if I am confident enough.
I use http://www.cleverbot.com fed back with http://www.google.com
In plain terms and easy to follow instructions, take the output from cleverbot, affix a term in the direction you wish to go, then enter it into google. Select the best output from google and feed it back into cleverbot as a response.
For tight structure, I use the principle of dialectics, oscillating between two terms for successive inputs to the A.I.
For instance, "green technology" vs "automobiles".
More complex structures can of course be created that are more natural than simple binary opposition.
Using names is very dangerous to the individuals concerned, and can cause death, ISIS take note.
