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: "towards microservices and beyond an incoming paradigm shift in distributed computing"
  Abstract: The microservice architecture is a style inspired by service-oriented computing that has recently started gaining popularity and that promises to change the way in which software is perceived, conceived and designed. In this paper we offer a short overview intended as a collection of bibliographic references and links in the field of Microservices Science and Engineering (MSE).
