  "Description": "An implementation of self-exciting point process model for\ninformation cascades, which occurs when many people engage in\nthe same acts after observing the actions of others (e.g. post\nresharings on Facebook or Twitter). It provides functions to\nestimate the infectiousness of an information cascade and\npredict its popularity given the observed history. See\nhttp://snap.stanford.edu/seismic/ for more information and\ndatasets.",
