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 "initial steps towards assessing the usability of a verification tool"):
  Abstract: In this paper we report the experience of using AutoProof to statically verify a small object oriented program. We identified the problems that emerged by this activity and we classified them according to their nature. In particular, we distinguish between tool-related and methodology-related issues, and propose necessary changes to simplify both tool and method.

Includes members:
  Member "autoproof auto active functional verification of object oriented programs":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "formality in software requirements")
  Member "the autoproof verifier usability by non experts and on standard code":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "towards a broader acceptance of formal verification tools the role of education")
  Member "flexible invariants through semantic collaboration":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "targeted synthesis for programming with data invariants")
  Member "on modelling and analysis of dynamic reconfiguration of dependable real time systems":
    also connected through other hyperedges:
