1. A computer program product for inducing a pattern of communication among a plurality of parties communicating information, the computer program product comprising: a non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising: 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 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 storing the transmission graph on a storage repository; predicting a propagation pattern of a 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.
5. The computer program product of claim 1 , wherein the parties include at least one transmitting party that transmits information about the topic, and at least one receiving party that receives the information about the topic from the at least one transmitting party; and further comprising, for certain communication paths along the transmission graph, determining a probability that the receiving party writes about the topic.
