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: "the ctu prague relational learning repository"
  Abstract: The aim of the CTU Prague Relational Learning Repository is to support machine learning research with multi-relational data. The repository currently contains 50 SQL databases hosted on a public MySQL server located at relational.fit.cvut.cz. A searchable meta-database provides metadata (e.g., the number of tables in the database, the number of rows and columns in the tables, the number of foreign key constraints between tables).
