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 "Automating impact analysis and regression test selection based on UML designs"):
  Abstract: We present a methodology and a tool to support test selection from regression test suites based on change analysis in object-oriented designs. We assume that designs are represented using the Unified Modeling Language (UML) and we propose a formal mapping between design changes and a classification of regression test cases, i.e., three categories: reusable, retestable, and obsolete. We provide evidence of the feasibility of the methodology and its usefulness by using our prototype tool on an industrial case study.
