AUTOMATIC ACCURACY ESTIMATION FOR AUDIO TRANSCRIPTIONS

摘要

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.

主权项

1. A method of assigning a confidence level to at least one axiom extracted from a text, comprising:
determining a number of accurate words in the text based on a spell check function; dividing a number of accurate words from the text by a total number of words in the text; 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, the at least one axiom, wherein the at least one axion is associated with at least one word from the text; and assigning a confidence level to the at least one axiom based on a result of the dividing and the assigning, wherein the confidence level is assigned based on an output of a Gaussian function applied to the result of the dividing and the assigning.
