All Implemented Interfaces:

ModuleListener

public class Brain

extends java.lang.Object

implements ModuleListener

The Brain is the central processing point for many different bits of information. It coordinates a discourse model, generator, salience list and salience tracker as they update for the semantic expressions which the Brain is asked to evaluate.
