Abstract
A user goal extracting unit extracts a user goal from an input statement 10 entered by a user. A system goal determining unit 15 determines a system goal in accordance with the user goal. A goal frame generating unit 17 generates a goal frame based on an action sequence knowledge corresponding to the system goal. An action feasibility judging unit 19 sets arguments for, and judges the feasibility of, an action in the goal frame. If the action is judged to be feasible, the action feasibility judging unit 19 outputs an action command to an external application 20. If the action is not judged to be feasible, the action feasibility judging unit 19 outputs a new system goal to the goal frame generating unit 17. The external application 20 outputs a result of execution of the action.
