public class IDemoRecommender

extends Interpreter

This class is an interpreter that converts information about a tour into possible interesting tour demos to visit. Another component (app/widget/interpreter) sends an interpret command to it with a list of visited demos and associated user interests, a list of user interests, and a complete list of possible demos and associated information (demo name, demo text description), and this interpreter returns potentially interesting demos that the user has not visited.
