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 "controlled natural language processing as answer set programming an experiment"):
  Abstract: Most controlled natural languages (CNLs) are processed with the help of a pipeline architecture that relies on different software components. We investigate in this paper in an experimental way how well answer set programming (ASP) is suited as a unifying framework for parsing a CNL, deriving a formal representation for the resulting syntax trees, and for reasoning with that representation. We start from a list of input tokens in ASP notation and show how this input can be transformed into a syntax tree using an ASP grammar and then into reified ASP rules in form of a set of facts. These facts are then processed by an ASP meta-interpreter that allows us to infer new knowledge.

Includes members:
  Member "a survey and classification of controlled natural languages":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "expressiveness and machine processability of knowledge organization systems kos an analysis of concepts and relations")
  Member "computing preferred answer sets by meta interpretation in answer set programming":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "generalizing modular logic programs")
