human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "on separation criterion and recovery algorithm for chain graphs"):
  Abstract: Chain graphs give a natural unifying point of view on Markov and Bayesian networks and enlarge the potential of graphical models for description of conditional independence structures. In the paper a direct graphical separation criterion for chain graphs, called c-separation, which generalizes the d-separation criterion for Bayesian networks is introduced (recalled). It is equivalent to the classic moralization criterion for chain graphs and complete in sense that for every chain graph there exists a probability distribution satisfying exactly conditional independencies derivable from the chain graph by the c-separation criterion. Every class of Markov equivalent chain graphs can be uniquely described by a natural representative, called the largest chain graph. A recovery algorithm, which on basis of the (conditional) dependency model induced by an unknown chain graph finds the corresponding largest chain graph, is presented.

  Member "an algorithm for deciding if a set of observed independencies has a causal explanation":

  Member "on the logic of causal models":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "probabilistic reasoning across the causal hierarchy")
  Member "chain graphs for learning":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "multi context models for reasoning under partial knowledge generative process and inference grammar")
