1. A computer-implemented system for cluster spine group arrangement, comprising: a set of spine groups each comprising one or more spines of clusters and at least one singleton cluster; a display; and a server comprising a central processing unit, memory, an input port to receive the spine groups, and an output port, wherein the central processing unit is configured to: identify unique spine groups within the set; place the unique spine groups in a center of a display; and arrange at least a portion of the remaining spine groups in the set extending radially from the unique spine groups in the display center.

A system according to claim 1 , wherein the central processing unit identifies the unique spine groups by determining a group concept score vector for each spine group based on concepts of the clusters in that group and identifying as the unique spine groups those spine groups that are dissimilar to the other spine groups based on the group concept scores.
