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 "cultural investment and urban socio economic development a geosocial network approach"):
  Abstract: Being able to assess the impact of government-led investment onto socio-economic indicators in cities has long been an important target of urban planning. However, owing to the lack of large-scale ...

Includes members:
  Member "measuring urban deprivation from user generated content":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "exploiting population activity dynamics to predict urban epidemiological incidence")
  Member "topological properties and temporal dynamics of place networks in urban environments":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "quantifying location sociality")
  Member "where businesses thrive predicting the impact of the olympic games on local retailers through location based services data":
    also connected through other hyperedges:

  Member "geo spotting mining online location based services for optimal retail store placement":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "under the hood of membership inference attacks on aggregate location time series")
