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 "vicious circle principle and logic programs with aggregates"):
  Abstract: The paper presents a knowledge representation language  #N#                       #N#                          #N#                         #N#            #N#             #N#                 #N#                    $\mathcal{A}log$#N#                 #N#             #N#        #N#                       #N#                     which extends ASP with aggregates. The goal is to have a language based on simple syntax and clear intuitive and mathematical semantics. We give some properties of  #N#                       #N#                          #N#                         #N#            #N#             #N#                 #N#                    $\mathcal{A}log$#N#                 #N#             #N#        #N#                       #N#                    , an algorithm for computing its answer sets, and comparison with other approaches.
