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 "do we really need to write documentation for a system case tool add ons generator editor for a precise documentation"):
  Abstract: One of the common problems of system development projects is that the system documentation is often outdated and does not describe the latest version of the system. The situation is even more complicated if we are speaking not about a natural language description of the system, but about its formal specification. In this paper we discuss how the problem could be solved by updating the documentation automatically, by generating a new formal specification from the model if the model is frequently changed.

Includes members:
  Member "human factors of formal methods":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a domain specific language for verifying software requirement constraints")
  Member "verified system development with the autofocus tool chain":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "towards readability aspects of probabilistic mode automata")
