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.
