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 "identification of promising research directions using machine learning aided medical literature analysis"):
  Abstract: The rapidly expanding corpus of medical research literature presents major challenges in the understanding of previous work, the extraction of maximum information from collected data, and the identification of promising research directions. We present a case for the use of advanced machine learning techniques as an aide in this task and introduce a novel methodology that is shown to be capable of extracting meaningful information from large longitudinal corpora, and of tracking complex temporal changes within it.

Includes members:
  Member "overcoming data scarcity of twitter using tweets as bootstrap with application to autism related topic content analysis":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "discovering topic structures of a temporally evolving document corpus")
  Member "using twitter to learn about the autism community":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "discovering topic structures of a temporally evolving document corpus")
  Member "sample targeted clinical trial adaptation":
    also connected through other hyperedges:
      (none)
