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 "a new finitely controllable class of tuple generating dependencies the triangularly guarded class"):
  Abstract: In this paper we introduce a new class of tuple-generating dependencies (TGDs) called triangularly-guarded (TG) TGDs. We show that conjunctive query answering under this new class of TGDs is decidable since this new class of TGDs also satisfies the finite controllability (FC) property. We further show that this new class strictly contains some other decidable classes such as weak-acyclic, guarded, sticky and shy. In this sense, the class TG provides a unified representation of all these aforementioned classes of TGDs.

Includes members:
  Member "existential rule languages with finite chase complexity and expressiveness":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "towards universal languages for tractable ontology mediated query answering")
  Member "acyclicity notions for existential rules and their application to query answering in ontologies":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "query inseparability for alc ontologies")
  Member "converging to the chase a tool for finite controllability":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "finite model reasoning over existential rules")
