Building on this observation, our technique for estimating the user's explicit meaning uses a probability threshold to select those individual frame elements which are most likely to be in the frame for a complete utterance, according to the predictive model.
at each partial result r j , we estimate the user's explicit meaning using a constructed frame: This approximation could work well if, in practice, the most probable frame elements prove to match fairly closely the user's non-incremental utterance meaning at the point this frame is constructed.
