12. The system of claim 10 , where, when grouping the documents into the plurality of clusters, the processor is further to: form the plurality of clusters based on at least one of a content-based clustering technique or a predictive-based clustering technique.
10. A system, comprising: a memory; and a processor, connected to the memory, to: group documents into a plurality of clusters, where subsets of the documents grouped, respectively, into the plurality of clusters, are duplicative and differ from documents grouped into other ones the plurality of clusters; determine a measure of quality for each of the documents; select a representative document, respectively, for two of the plurality of clusters, based on the measure of quality; determine a target document associated with each of the representative documents; determine addresses associated with the target documents; determine that the target documents are duplicative based on the addresses associated with the target documents; and combine the target documents and the two of the plurality of clusters into a combined single cluster, in response to determining that the target documents are duplicative.
