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 "k p planarity a generalization of hybrid planarity"):
  Abstract: A graph $G$ is $(k,p)$-planar if its vertices can be partitioned into clusters of size at most $k$ such that $G$ admits a drawing where: (i) Each cluster is associated with a closed region in the plane (called cluster region) that is topologically equivalent to a disk; (ii) Cluster regions are pairwise disjoint; (iii) Each vertex of a cluster is associated with at most $p$ distinct points (called ports) on the boundary of its cluster region; (iv) Each edge $(u,v)$ is a Jordan arc connecting a port of $u$ with a port of $v$; and (v) Edges connecting different clusters do not cross each other and do not intersect any cluster region, with the only exception for end-points. We first ask a Tur\'{a}n-type question and give a tight upper bound on the number of edges of $(k,p)$-planar graphs. We then study the complexity of the $(k,p)$-planarity testing problem and prove that $(4,1)$-planarity testing and $(2,2)$-planarity testing are both NP-complete problems. Finally, motivated by the NP-completeness of $(2,2)$-planarity testing, we investigate the combinatorial properties of $(2,2)$-planar graphs and study their relationship with $1$-planar graphs, describing families of $1$-planar graphs that are $(2,2)$-planar as well as families that are not.
