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 "coalition formation and combinatorial auctions applications to self organization and self management in utility computing"):
  Abstract: In this paper we propose a two-stage protocol for resource management in a hierarchically organized cloud. The rst stage exploits spatial locality for the formation of coalitions of supply agents; the second stage, a combinatorial auction, is based on a modied proxy-based clock algorithm and has two phases, a clock phase and a proxy phase. The clock phase supports price discovery; in the second phase a proxy conducts multiple rounds of a combinatorial auction for the package of services requested by each client. The protocol strikes a balance between low-cost services for cloud clients and a decent prot for the service providers. We also report the results of an empirical investigation of the combinatorial auction stage of the protocol.
