Patent ID: 7440622

Claim:
A system for arranging concept clusters in thematic neighborhood relationships in a shaped two-dimensional visual display space, comprising: a clustering module to select a set of clusters from a concept space comprising a multiplicity of clusters with concepts extracted to visualize document content; a theme generator to identify a theme in each of a plurality of the clusters, each theme comprising at least one such concept ranked within the cluster; a spine placement module to logically form a plurality of best fit of candidate spines comprising clusters sharing at least one common theme by assigning one or more of the clusters to one or more candidate spines having a substantially best fit, to identify one or more of the best fit candidate spines sufficiently unique from each other such best fit candidate spine and to place the identified best fit candidate spines in a visual display space; and a spine group placement module to evaluate a similarity between each non-identified best fit candidate spine and each previously placed best fit candidate spine and to place each non-identified best fit candidate spine in the visual display space relative to an anchor cluster on one of the previously placed best fit candidate spines that is sufficiently similar to the non-identified best fit candidate spine.
