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 "analysis and study on text representation to improve the accuracy of the normalized compression distance"):
  Abstract: The huge amount of information stored in text form makes methods that deal with texts really interesting. This thesis focuses on dealing with texts using compression distances. More specifically, the thesis takes a small step towards understanding both the nature of texts and the nature of compression distances. Broadly speaking, the way in which this is done is exploring the effects that several distortion techniques have on one of the most successful distances in the family of compression distances, the Normalized Compression Distance -NCD-.

Includes members:
  Member "evaluating the impact of information distortion on normalized compression distance":
    also connected through other hyperedges:
      (none)
  Member "analyzing worms and network traffic using compression":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "identifying cover songs using information theoretic measures of similarity")
  Member "the google similarity distance":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "semantic relatedness for keyword disambiguation exploiting different embeddings")
  Member "the similarity metric":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "max margin class imbalanced learning with gaussian affinity")
