US Patent 7698335 Cluster organization of electronically-stored items

Clusters are described which may be utilized to organize electronically-stored items. A variety of techniques may be employed using the clusters to organize the items. For instance, the clusters may be automatically generated and then modified by a user to classify the items as desired such that a modification made to a single item is propagated to other similar items. Therefore, the single item and the other similar items may be clustered automatically through interaction with the single item.
