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: "development of formal models algorithms procedures engineering and functioning of the software system instrumental complex for ontological engineering purpose"
  Abstract: The given paper considered a generalized model representation of the software system "Instrumental complex for ontological engineering purpose". Represented complete software system development process. Developed relevant formal models of the software system "Instrumental complex for ontological engineering purpose", represented as mathematical expressions, UML diagrams, and also described the three-tier architecture of the software system "Instrumental complex for ontological engineering purpose" in a client-server environment.

Connected through hyperedge HE-1 (induced by source paper "distributional semantic modeling a revised technique to train term word vector space models applying the ontology related approach"):
