Abstract: Methods and apparatus for determining a tone differential between a given segment of a document and a larger segment of the document. The tone differential may be based on comparison of a first tone associated with the given segment and a second tone associated with the larger segment. The tone differential is indicative of the variance between the tone of the given segment and the tone of the larger segment.
