human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups authors who co-authored the same paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "A schema-based translation of XQuery updates"):
  Abstract: We address the problem of translating XQuery updates to plain XQuery expressions. The resulting XQuery code reconstructs the mutable state (the updated XML data), reflecting the updated values in the new state. The translation is done using source-to-source, compositional transformations only. Unlike related approaches that use framework-specific algebras to achieve a similar goal, our work can be incorporated into any existing XQuery engine.
