Computer-implemented system and method for providing a display of clusters

1. A computer-implemented system for providing a display of clusters, comprising:

a processor;

a display module to present a plurality of cluster spines in a two-dimensional display, wherein each cluster spine comprises a vector of document clusters;

a compass positioned over at least a portion of the clusters of one or more of the cluster spines;

spine labels provided for at least one of the cluster spines within the compass and placed around a circumference of the compass;

a pinning module to pin one of the spine labels to the compass at a fixed location;

a reorientation module to reorient the compass within the display; and

the two-dimensional display to display the pinned spine label at the fixed location on the reoriented compass.

2. A system according to claim 1 , further comprising:

further spine labels determined for those cluster spines encompassed by the reoriented compass.

3. A system according to claim 1 , further comprising:

a cluster label displayed for one such cluster within the compass when at least one of that cluster is selected and a pointer hovers over that cluster, wherein the cluster label comprises a concept shared by one or more documents in that cluster.

4. A system according to claim 1 , further comprising:

a further compass provided within the two-dimensional display.

5. A system according to claim 4 , further comprising:

a label determination module to determine the spine labels for the compass and the further compass by generating a set of spine labels for the cluster spines that appear within one of the compasses that is concentric to the other compass and by generating a different set of spine labels for those cluster spines that appear only within the other compass.

6. A system according to claim 1 , further comprising:

a group generator to generate groups of the cluster spines, comprising:

a cluster spine selection module to select those cluster spines that are unique;

a grafting module to graft one or more remaining cluster spines on one such unique cluster spine as one such cluster spine group.

7. A system according to claim 6 , further comprising:

a placement module to place the cluster spine groups within the two-dimensional display by arranging one or more of the cluster spine groups circumferentially to a circle defined within the two-dimensional display.

8. A system according to claim 1 , further comprising:

a pointer to connect the cluster spine and the associated spine label, wherein the pointer connects to an outermost cluster of the cluster spine.

9. A system according to claim 1 , further comprising:

a spine label module to present a predefined number of spine labels for display within the two-dimensional display.

10. A system according to claim 1 , wherein each spine label comprises a common concept that connects the clusters appearing in the associated cluster spine.

11. A computer-implemented method for providing a display of clusters, comprising:

presenting a plurality of cluster spines in a two-dimensional display, wherein each cluster spine comprises a vector of document clusters;

positioning a compass over at least a portion of the clusters of one or more of the cluster spines;

placing spine labels for at least one of the spines encompassed by the compass around a circumference of the compass;

pinning one of the spine labels to the compass at a fixed location;

reorienting the compass within the display; and

displaying the pinned spine label at the fixed location on the reoriented compass.

12. A method according to claim 11 , further comprising:

determining further spine labels for those cluster spines encompassed by the reoriented compass.

13. A method according to claim 11 , further comprising:

displaying for one such cluster within the compass, a cluster label when at least one of that cluster is selected and a pointer hovers over that cluster, wherein cluster label comprises a concept shared by one or more documents in that cluster.

14. A method according to claim 11 , further comprising:

providing a further compass within the two-dimensional display.

15. A method according to claim 14 , further comprising:

determining the spine labels for the compass and the further compass, comprising:

generating a set of spine labels for the cluster spines that appear within one of the compasses that is concentric to the other compass; and

generating a different set of spine labels for those cluster spines that appear only within the other compass.

16. A method according to claim 11 , further comprising:

generating groups of the cluster spines, comprising:

selecting those cluster spines that are unique;

grafting one or more remaining cluster spines on one such unique cluster spine as one such cluster spine group.

17. A method according to claim 16 , further comprising:

placing the cluster spine groups within the two-dimensional display by arranging one or more of the cluster spine groups circumferentially to a circle defined within the two-dimensional display.

18. A method according to claim 11 , further comprising:

connecting the cluster spine and the associated spine label via a pointer, wherein the pointer connects to an outermost cluster of the cluster spine.

19. A method according to claim 11 , further comprising:

providing a predefined number of spine labels for the cluster spines within the compass.

20. A method according to claim 11 , wherein each spine label comprises a common concept that connects the clusters appearing in the associated cluster spine.
