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: "n permutability and linear datalog implies symmetric datalog"
  Abstract: We show that if $\mathbb A$ is a core relational structure such that $CSP(\mathbb{A})$ can be solved by a linear Datalog program, and $\mathbb A$ is $n$-permutable for some $n$, then $CSP(\mathbb A)$ can be solved by a symmetric Datalog program (and thus $CSP(\mathbb{A})$ lies in deterministic logspace). At the moment, it is not known for which structures $\mathbb A$ will $CSP(\mathbb{A})$ be solvable by a linear Datalog program. However, once somebody obtains a characterization of linear Datalog, our result immediately gives a characterization of symmetric Datalog.
