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 "answering comparative questions better than ten blue links"):
  Abstract: We present CAM (comparative argumentative machine), a novel open-domain IR system to argumentatively compare objects with respect to information extracted from the Common Crawl. In a user study, the participants obtained 15% more accurate answers using CAM compared to a "traditional" keyword-based search and were 20% faster in finding the answer to comparative questions.

Includes members:
  Member "categorization of comparative sentences for argument mining":
    also connected through other hyperedges:
      (none)
  Member "building a web scale dependency parsed corpus from commoncrawl":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "the two pass softmax algorithm")
  Member "what is the essence of a claim cross domain claim identification":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "tacam topic and context aware argument mining")
  Member "social media argumentation mining the quest for deliberateness in raucousness":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "categorizing comparative sentences")
  Member "understanding and detecting supporting arguments of diverse types":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "tacam topic and context aware argument mining")
  Member "xgboost a scalable tree boosting system":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "monotonic cardinality estimation of similarity selection a deep learning approach")
