Patent ID: 7271804

Claim:
A system for generating a two-dimensional spatial arrangement of a cluster rendering, comprising: clusters stored in a storage to represent concepts and terms extracted from a set of documents; a set of the stored clusters selected with each selected cluster sharing a common theme comprising one or more of the extracted concepts and terms that are shared; and a placement module to place the set of the stored clusters into a grouping, comprising: an anchor point selector submodule to choose one of the selected clusters and to determine an anchor point on the chosen cluster that is located on an open edge of the chosen cluster along a vector defined from a center of the chosen cluster, wherein the vector intersects the anchor point; and a cluster placement submodule to place a center of a further selected cluster outside of the anchor point on the vector and to limit overlap of the chosen cluster and the further selected cluster; and an arrangement submodule to arrange one or more of the remaining selected clusters into an arrangement of clusters that each have a center originating outside of the anchor point and on the vector; and a display and visualization module to display the grouping via a display.
