Method and System of Optimal Selection Strategy for Statistical Classifications in Dialog Systems
First Claim
1. A dialog system comprising:
- a classifier coupled to a processor and configured to generate a plurality of predictions on a dialog act corresponding to an utterance received at an input; and
a decision component coupled to the processor and configured to generate a plurality of probabilities each of which corresponds to a prediction, dynamically select a set of predictions from the plurality of predictions, and classify the utterance according to an accumulated probability of the set of predictions.

Abstract
An optimal selection or decision strategy is described through an example that includes use in dialog systems. The selection strategy or method includes receiving multiple predictions and multiple probabilities. The received predictions predict the content of a received input and each of the probabilities corresponds to one of the predictions. In an example dialog system, the received input includes an utterance. The selection method includes dynamically selecting a set of predictions from the received predictions by generating ranked predictions. The ranked predictions are generated by ordering the plurality of predictions according to descending probability.
