1. A method of assigning a confidence level to at least one axiom extracted from a text, comprising:
- comparing at least one word from the text to a dictionary;
determining a number of accurate words based on the comparing;
dividing the number of accurate words by a total number of words in the transcription;
assigning a greater weight to at least one word exceeding a predetermined number of characters as compared to at least one other word below the predetermined number of characters;
retrieving, from a data structure, at least one axiom associated with at least one word from the text; and
assigning the confidence level to the at least one axiom based on a result of the dividing and the assigning.

Abstract
Embodiments of the present invention provide an approach for estimating the accuracy of a transcription of a voice recording. Specifically, in a typical embodiment, each word of a transcription of a voice recording is checked against a customer-specific dictionary and/or a common language dictionary. The number of words not found in either dictionary is determined. An accuracy number for the transcription is calculated from the number of said words not found and the total number of words in the transcription.

9. A system for assigning a confidence level to at least one axiom extracted from a text, comprising:
-
a memory medium comprising instructions; a bus coupled to the memory medium; and an audio transcription tool coupled to the bus that when executing the instructions causes the system to; compare at least one word from the text to a dictionary; determine a number of accurate words based on the comparing; divide the number of accurate words by a total number of words in the transcription; assign a greater weight to at least one word exceeding a predetermined number of characters as compared to at least one other word below the predetermined number of characters; retrieve, from a data structure, at least one axiom associated with at least one word from the text; and assign the confidence level to the at least one axiom based on a result of the dividing and the assigning. - View Dependent Claims (10, 11, 12, 13, 14)

15. A computer program product for assigning a confidence level to at least one axiom extracted from a text, the computer program product comprising a computer readable storage medium, and program instructions stored on the computer readable storage medium, to:
-
compare at least one word from the text to a dictionary; determine a number of accurate words based on the comparing; divide the number of accurate words by a total number of words in the transcription; assign a greater weight to at least one word exceeding a predetermined number of characters as compared to at least one other word below the predetermined number of characters; retrieve, from a data structure, at least one axiom associated with at least one word from the text; and assign the confidence level to the at least one axiom based on a result of the dividing and the assigning. - View Dependent Claims (16, 17, 18, 19, 20)
