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 "definition of internet of things iot cyber risk discussion on a transformation roadmap for standardisation of regulations risk maturity strategy design and impact assessment"):
  Abstract: A comparative empirical analysis is performed to define a high-level potential target state followed by a high-level transformation roadmap, describing how company can achieve their target state, based on their current state. The transformation roadmap is used to adapt the Goal-Oriented Approach and the IoT Micro Mart model.
