1. A method for graphically characterizing statements about an object, comprising:

  • applying, as a result of computing hardware and programmable memory, frame extraction, to a first corpus, in order to attempt to identify, for each statement of the corpus, an object and a sentiment expressed about the object;

    identifying, as a result of computing hardware and programmable memory, a first object-specific corpus, that is a subset of the first corpus, where all the statements of the first object-specific corpus are about a same first object;

    categorizing, as a result of computing hardware and programmable memory, a sentiment of each statement, of the first object-specific corpus;

    categorizing a polarity of each statement, of the first object-specific corpus;

    categorizing an intensity of each statement, of the first object-specific corpus;

    determining, as a result of computing hardware and programmable memory, a net polarity measure as a function of the polarity categorization and a net intensity measure as a function of the intensity categorization;

    producing, as a result of computing hardware and programmable memory, a first graphical representation, of the first object-specific corpus;

    placing the first graphical representation, relative to a first axis, in accordance with the net polarity measure; and

    placing the first graphical representation, relative to a second axis, in accordance with the net intensity measure.
