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 transcription 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; retrieving, from a data structure, 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.
