Method of phrase verification with probabilistic confidence tagging
First Claim
1. A method of phrase verification with probabilistic confidence tagging, comprising the steps of:
- receiving an utterance;
parsing the received utterance to find a concept sequence;
producing a plurality of tag sequences corresponding to the concept sequence;
calculating a first score of each of the tag sequences; and
selecting the tag sequence of the highest first score as a most probable tag sequence, and selecting the tags in the most probable tag sequence as most probable confidence tags.

Abstract
A method of phrase verification to verify a phrase not only according to its confidence measures but also according to neighboring concepts and their confidence tags. First, an utterance is received, and the received utterance is parsed to find a concept sequence. Subsequently, a plurality of tag sequences corresponding to the concept sequence is produced. Then, a first score of each of the tag sequences is calculated. Finally, the tag sequence of the highest first score is selected as the most probable tag sequence, and the tags contained therein are selected as the most probable confidence tags, respectively corresponding to the concepts in the concept sequence.

5. A method of phrase verification with probabilistic confidence tagging, comprising the steps of:
-
receiving an utterance;
parsing the received utterance to find a concept sequence;
assessing a or a plurality of confidence measures of each of concepts in the concept sequence;
producing a plurality of tag sequences corresponding to the concept sequence;
calculating a first score of each of the tag sequences;
calculating a second score of each of the tag sequences;
proceeding a weighted calculation on the first score and second score, thus a total score is acquired; and
selecting the tag sequence of the highest total score as a most probable tag sequence, and selecting the tags in the most probable tag sequence as most probable confidence tags. - View Dependent Claims (6, 7, 8, 9)
