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 "towards the characterization of individual users through web analytics"):
  Abstract: We perform an analysis of the way individual users navigate in the Web. We focus primarily in the temporal patterns of they return to a given page. The return probability as a function of time as well as the distribution of time intervals between consecutive visits are measured and found to be independent of the level of activity of single users. The results indicate a rich variety of individual behaviors and seem to preclude the possibility of defining a characteristic frequency for each user in his/her visits to a single site.

Includes members:
  Member "what s in a session tracking individual behavior on the web":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "random surfers on a web encyclopedia")
  Member "remembering what we like toward an agent based model of web traffic":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "agents bookmarks and clicks a topical model of web navigation")
  Member "human dynamics revealed through web analytics":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a model for meme popularity growth in social networking systems based on biological principle and human interest dynamics")
  Member "rhythms of social interaction messaging within a massive online network":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "designing for health chatbots")
  Member "novelty and collective attention":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "modeling the popularity of twitter hashtags with master equations")
