A computer-implemented method includes receiving, by one or more computer systems, first information from a first channel and second information from a second channel; merging the first information with the second information; applying an unsupervised clustering model to the merged information; and generating, based on results of the applying, a cross-channel cluster, the cross-channel cluster including (i) a portion of the first information associated with a subject matter, and (ii) a portion of the second information associated with the subject matter.
