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 "news and the city understanding online press consumption patterns through mobile data"):
  Abstract: The always increasing mobile connectivity affects every aspect of our daily lives, including how and when we keep ourselves informed and consult news media. By studying mobile web data, provided by one of the major Chilean telecommunication companies, we investigate how different cohorts of the population of Santiago De Chile consume news media content through their smartphones. We address the issue of inequalities in the access to information, trying to understand to what extent socio-demographic factors impact the preferences and habits of the users.

Includes members:
  Member "power structure in chilean news media":
