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 "coalgebraic characterizations of context free languages"):
  Abstract: htmlabstractIn this article, we provide three coalgebraic characterizations of the class of#R##N#context-free languages, each based on the idea of adding coalgebraic structure to an existing#R##N#algebraic structure by specifying output-derivative pairs. Final coalgebra semantics then#R##N#gives an interpretation function into the nal coalgebra of all languages with the usual#R##N#output and derivative operations. The rst characterization is based on systems, where#R##N#each derivative is given as a nite language over the set of nonterminals; the second#R##N#characterization on systems where derivatives are given as elements of a term-algebra; and#R##N#the third characterization is based on adding coalgebraic structure to a class of closed#R##N#(unique) xed point expressions. We prove equivalences between these characterizations,#R##N#discuss the generalization from languages to formal power series, as well as the relationship#R##N#to the generalized powerset construction.
