human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "type checking liveness for collaborative processes with bounded and unbounded recursion"
  Abstract: We present the first session typing system guaranteeing request-response#N#liveness properties for possibly non-terminating communicating processes. The#N#types augment the branch and select types of the standard binary session types#N#with a set of required responses, indicating that whenever a particular label#N#is selected, a set of other labels, its responses, must eventually also be#N#selected. We prove that these extended types are strictly more expressive than#N#standard session types. We provide a type system for a process calculus similar#N#to a subset of collaborative BPMN processes with internal (data-based) and#N#external (event-based) branching, message passing, bounded and unbounded#N#looping. We prove that this type system is sound, i.e., it guarantees#N#request-response liveness for dead-lock free processes. We exemplify the use of#N#the calculus and type system on a concrete example of an infinite state system.
