RST and facial expression

[Andrew n marshall]

Hi,
  I'm a programmer working with tutoring agents and animated agents.  I
recently stubbled across RST and beleive there is a large potential for use
in my work.  My particular interests focus on RST applications to
dialogues, but I have yet to find much information on this.  Is there any
know work in progress in this feild?


Also, from the archives:
