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: "language asp f with arithmetic expressions and consistency restoring rules"
  Abstract: In this paper we continue the work on our extension of Answer Set Programming by non-Herbrand functions and add to the language support for arithmetic expressions and various inequality relations over non-Herbrand functions, as well as consistency-restoring rules from CR-Prolog. We demonstrate the use of this latest version of the language in the representation of important kinds of knowledge.

Connected through hyperedge HE-1 (induced by source paper "modular action language"):
  with members:
    - "sparc sorted asp with consistency restoring rules"
    - "functional answer set programming"
    - "the dlv system for knowledge representation and reasoning"
    - "diagnostic reasoning with a prolog"
    - "stable models and an alternative logic programming paradigm"

Connected through hyperedge HE-2 (induced by source paper "a refinement based architecture for knowledge representation and reasoning in robotics"):
  with members:
    - "an asp based architecture for autonomous uavs in dynamic environments progress report"
    - "towards an asp based architecture for autonomous uavs in dynamic environments extended abstract"
    - "model checking with probabilistic tabled logic programming"
    - "probabilistic reasoning with answer sets"
    - "diagnostic reasoning with a prolog"
