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: "comparative study of virtual machines and containers for devops developers"
  Abstract: In this work, we plan to develop a system to compare virtual machines with container technology. We would devise ways to measure the administrator effort of containers vs. Virtual Machines (VMs). Metrics that will be tested against include human efforts required, ease of migration, resource utilization and ease of use using containers and virtual machines.
