1. A computer-implemented method for estimating the accuracy of a transcription of a voice recording, comprising:

  • calculating an accuracy number by dividing a number of accurate words in the transcript on by a total number of words in the transcription;

    assigning a greater weight to at least one word exceeding a predefined number of characters as compared to at least one other word below the predetermined number of characters;

    automatically extracting using natural language processing, from a data structure that is one of a common language dictionary, customer specific dictionary or a knowledge base, a set of axioms associated with at least one of the words in the transcription, wherein the set of axioms comprises a computer-parsable definition of a relationship of data to the at least one of the words; and

    assigning a confidence level to each axiom of the set of axioms based on a result of the dividing and the assigning of weight, wherein the confidence level is assigned based on an output of a Gaussian function applied to a result of the dividing and the assigning of weight.
