human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "government mandated blocking of foreign web content"
  Abstract: Blocking of foreign Web content by Internet access providers has been a hot topic for the last 18 months in Germany. Since fall 2001 the state of North-Rhine-Westphalia very actively tries to mandate such blocking. This paper will take a technical view on the problems imposed by the blocking orders and blocking content at access or network provider level in general. It will also give some empirical data on the effects of the blocking orders to help in the legal assessment of the orders.
