1. A computer program product having executable instruction codes for inducing a pattern of communication among a plurality of parties communicating information, comprising the executable instructions for: receiving during a first episode, for each party of a plurality of parties information that describes a topic that is discussed by at least some parties of the plurality of parties at a predetermined and a time of occurrence of discussion; preparing a transmission graph illustrative of the pattern of communication, wherein the transmission graph illustrates at least some of the parties as nodes and a plurality of edges that interconnect at least some of the nodes, and wherein the transmission graph establishes a pattern of distribution of propagation of discussion of the topic among the plurality of parties; and outputting the transmission graph storing the transmission graph on a storage repository; predicting a propagation pattern of the second episode using the pattern of distribution of propagation established for the first episode and an initial fragment of propagation of discussion of a subsequent second episode; and outputting on a display of a computer system the propagation pattern of the second episode.
