US Patent 8676795 Dynamic visual representation of phrases

A plurality of phrases may be extracted from documents associated with one or more document sources. The plurality of phrases may be filtered and processed to determine a frequency in which the plurality of phrases appear in the documents and/or a number of the document sources in which each phrase appears. A weight may be assigned to each of the phrases and, based at least in part on the assigned weight, a visual representation of the plurality of phrases may be presented. The visual representation may be dynamically updated based at least in part on an updated frequency or an updated total number of document sources associated with any one of the plurality of phrases.
