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 "system model based simulation of uml models"):
  Abstract: Previous work has presented our ongoing eorts to dene a \reference semantics" for the UML, that is, a mathematically dened system model that is envisaged to cover all of the UML eventually, and that also carefully avoids the introduction of any unwarranted restric- tions or biases. Due to the use of underspecication , the system model is not executable. This paper shows how the system model can serve as the basis for a highly customizable execution and simulation environment for the UML. The design and implementation of a prototype of such an en- vironment is described and its use for the experimentation with dierent semantic variation points is illustrated.

  Member "integrated definition of abstract and concrete syntax for textual languages":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "modeling reusable platform independent robot assembly processes")
