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: "making sense of global collaboration dynamics developing a methodological framework to study dis similarities between country disciplinary profiles and choice of collaboration partners"
  Abstract: This paper presents a novel methodological framework by which the effects of globalization on international collaboration can be studied and understood. Using the cosine similarity of the disciplinary and partner profiles of countries by collaboration types it is possible to analyse the effects of globalization and the costs and benefits of an increasing global networked research system.

Connected through hyperedge HE-1 (induced by source paper "the differing meanings of indicators under different policy contexts the case of internationalisation"):
