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: "universal structures and the logic of forbidden patterns"
  Abstract: Forbidden Patterns Problems (FPPs) are a proper generalisation of Constraint#N#Satisfaction Problems (CSPs). However, we show that when the input is connected#N#and belongs to a class which has low tree-depth decomposition (e.g. structure#N#of bounded degree, proper minor closed class and more generally class of#N#bounded expansion) any FPP becomes a CSP. This result can also be rephrased in#N#terms of expressiveness of the logic MMSNP, introduced by Feder and Vardi in#N#relation with CSPs. Our proof generalises that of a recent paper by Nesetril#N#and Ossona de Mendez. Note that our result holds in the general setting of#N#problems over arbitrary relational structures (not just for graphs).
