The invention provides a computer-implemented method for analyzing a piece of text. The method comprises truncating one or more characters of the text into one or more block units each having at least one character. The method includes sorting the one or more block units for one or more unique block units and comparing the one or more unique block units with a grading database to thereby assign a grade to each of the one or more unique block units. An overall grade for the piece of text may be determined based on one or more of the grades assigned to each of the one or more unique block units. The overall grade of the text may be derived from successive truncating of the text into block units of increasing size and the successive processing of such block units.
