Abstract: Systems and methods are provided for analyzing text within digital document. In some cases the analysis can include receiving and/or generating a digital document with processing circuitry and determining a distribution of each of a plurality of document terms based on occurrences of the document terms within a text sample and occurrences of sample terms within the text sample. Processing circuitry may be further used to determine a distribution characteristic for each of the plurality of document terms. The distribution characteristic for each document term can provide a measure of a characteristic of each respective document term's distribution. In some cases a characterization is provided of the text in the digital document with the processing circuitry based on the distribution characteristic of at least one of the plurality of document terms.
