Claim:
A system for using keywords to merge document clusters, the system comprising: one or more processors; and a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to: distribute a plurality of documents into a plurality of document clusters, wherein the plurality of document clusters comprise a first document cluster comprising a first plurality of documents and a second document cluster comprising a second plurality of documents; create a template associated with the first document cluster, wherein the template comprises a plurality of keywords associated with at least most of the first plurality of documents; calculate a distance between keyword location information associated with the template and word location information associated with a document in the second document cluster, wherein the keyword location information comprises information indicating a location of a keyword in the template relative to other keywords in the template, and wherein the word location information comprises information indicating a location of a word in the document relative to other words in the document; determine whether the distance is less than a threshold value; and merge the second document cluster with the first document cluster in response to a determination that the distance is less than the threshold value.
