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 "non monotonic reasoning and the reversibility of belief change"):
  Abstract: Traditional approaches to non-monotonic reasoning fail to satisfy a number of plausible axioms for belief revision and suffer from conceptual difficulties as well. Recent work on ranked preferential models (RPMs) promises to overcome some of these difficulties. Here we show that RPMs are not adequate to handle iterated belief change. Specifically, we show that RPMs do not always allow for the reversibility of belief change. This result indicates the need for numerical strengths of belief.

Includes members:
  Member "what does a conditional knowledge base entail":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a reconstruction of the multipreference closure")
  Member "nonmonotonic reasoning preferential models and cumulative logics":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on the existence of characterization logics and fundamental properties of argumentation semantics")
