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 "hott formalisation in coq dependency graphs ml4pg"):
  Abstract: This note is a response to Bas Spitter's email of 28 February 2014 about ML4PG: #R##N#"We (Jason actually) are adding dependency graphs to our HoTT library: this https URL#R##N#I seem to recall that finding the dependency graph was a main obstacle preventing machine learning to be used in Coq. However, you seem to have made progress on this. What tool are you using? this https URL ? Or another tool? Would it be easy to use your ML4PG on the HoTT library?" #R##N#This note gives explanation of how ML4PG can be used in the HoTT library and how ML4PG relates to the two kinds of Dependency graphs available in Coq.
