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: "reflective visualisation and verbalisation of unconscious preference"
  Abstract: A method is presented that helps persons become aware of their unconscious preferences, and convey them to others in the form of verbal explanation. The method combines the concepts of reflection, visualisation, and verbalisation. The method was tested in an experiment where the unconscious preferences of the subjects for artworks were investigated. We learned two lessons. The persons become aware of their unconscious preferences by verbalising weak preferences as compared with strong preferences through discussion over preference diagrams. They overcome the personal differences and foster the mutual understanding by adjusting the granularity of visualisation.

Connected through hyperedge HE-1 (induced by source paper "node discovery in a networked organization"):
  with members:
    - "learning the structure of dynamic probabilistic networks"
    - "analysing covert social network foundation behind terrorism disaster"
    - "network inference from co occurrences"
    - "search in power law networks"
