human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups authors who co-authored the same paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "A knowledge-based application definition system"):
  Abstract: The design of an experimental consultation system, here called ADS, aimed at providing expert-level assistance to (nonprogrammer) specialists in defining medically-oriented, sensor-based applications is considered. The heart of the system is a knowledge base containing extensive static descriptions of the problem domain and mechanisms for instantiating elements of a subject application.

Includes members:
  Member "An overview of KRL, a Knowledge Representation Language":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "GUS, a frame-driven dialog system")
