Patent ID: 8204988

Claim:
A computer-implemented system for modeling and analyzing the time evolution of social communication networks and a content related to such networks, said system comprising: an input device configured for receiving data representing a social communication network; a processing unit coupled to said input device for: (a) constructing a multi-mode tensor having one or a plurality of content dimensions and one or a plurality of network dimensions, said constructing being performed at each of a plurality of successive time intervals; (b) decomposing the multi-mode tensor into a core tensor and a set of factor matrices, one factor matrix for each mode; (c) modeling each mode of the tensor, wherein the modeling comprises treating each corresponding factor matrix as a low-dimensional representation of that mode, and grouping rows of each factor matrix into clusters based on a distance measure; (d) modeling a cross-mode correlation, wherein the cross-mode correlation comprises clustering each modeled mode of the multi-mode tensor, enumerating all combinations of clusters across different modes and identifying the cross-mode clusters that induce dense sub-tensors; and (e) generating a visualization of the modeled cross-mode correlation; and an output device configured for visualizing the modeled cross-mode correlation.
