Recursive agglomerative clustering of time-structured communications

Abstract

An example method of document cluster labeling comprises: selecting a current document cluster of a plurality of document clusters (e.g., the current document cluster can have documents organized using a DBSCAN or OPTICS algorithm); initializing a label associated with the current document cluster; selecting a term from a list of terms comprised by the document cluster; appending the term to the label associated with the current document cluster; responsive to determining that the label is found in a label dictionary, iteratively selecting a next term from the list of terms comprised by the document cluster and appending the next term to the label associated with the current document cluster; responsive to failing to locate the label in the label dictionary, inserting the label into the label dictionary; and associating the label with the current document cluster.
