12. The method of claim 1 , further comprising: producing a second corpus, containing statements within a second temporal range that is different from a first temporal range of the statements of the first corpus; applying frame extraction, to the second corpus, in order to attempt to identify, for each statement of the corpus, an object and a sentiment expressed about the object; identifying a second object-specific corpus, that is a subset of the second corpus, where all the statements of the second object-specific corpus are about the same first object as the first object-specific corpus; categorizing the sentiment of each statement, of the second object-specific corpus; determining a net metric value as a function of the categorization of the second object-specific corpus; and producing a second graphical representation, of the second object-specific corpus, that is placed according to the second net metric.

The method of claim 12 , wherein producing a second graphical representation further comprises: placing the second graphical representation relative to a temporal axis, with the first graphical representation occupying a differing position relative to the temporal axis.
