human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "multi user privacy the gray wyner system and generalized common information"
  Abstract: The problem of preserving privacy when a multivariate source is required to be revealed partially to multiple users is modeled as a Gray-Wyner source coding problem with K correlated sources at the encoder and K decoders in which the kth decoder, k = 1, 2, ...,K, losslessly reconstructs the kth source via a common link and a private link. The privacy requirement of keeping each decoder oblivious of all sources other than the one intended for it is introduced via an equivocation constraint at each decoder such that the total equivocation summed over all decoders is E. The set of achievable rates-equivocation tuples is completely characterized. Using this characterization, two different definitions of common information are presented and are shown to be equivalent.
