摘要: Using the concepts of stimulus and response frames scheduled Knowledge source instantiations, competition among alternative responses, goals, desirability a knowledge instantiation, general attentional control mechanism is developed. This focusing facilitates experimental evaluation variety specific policies (such as best-first, bottom-up, top-down search strategies) allows modular addition specialized heuristics for speech understanding task. Empirical results demonstrate effectiveness principles, possible directions future research are considered.
