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 "cities as they could be artificial life and urban systems"):
  Abstract: The metaphor of cities as organisms has a long history in urban planning, and a few urban modeling approaches have explicitly been linked to Artificial Life. We propose in that paper to explore the extent of Artificial Life and Artificial Intelligence application to urban issues, by constructing and exploring a citation network of around 225,000 papers. It shows that most of the literature is indeed application of methodologies and a rather strong modularity of approaches. We finally develop ALife concepts which have a strong potential for the development of new urban theories.

Includes members:
  Member "empowering open science with reflexive and spatialised indicators":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "conclusion perspectives on urban theories")
  Member "exploration of an interdisciplinary scientific landscape":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "conclusion perspectives on urban theories")
