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: "four commentaries on the use of students and professionals in empirical software engineering experiments"
  Abstract: Four commentaries on the use of students and professionals in empirical software engineering experiments

Connected through hyperedge HE-1 (induced by source paper "automating app review response generation"):
  with members:
    - "what you say and how you say it joint modeling of topics and discourse in microblog conversations"
    - "a benchmark study on sentiment analysis for software engineering research"
    - "the design and implementation of xiaoice an empathetic social chatbot"
    - "topic memory networks for short text classification"
    - "essmart way to manage user requests"
    - "harvesting paragraph level question answer pairs from wikipedia"
    - "automatically generating commit messages from diffs using neural machine translation"
    - "steering output style and topic in neural response generation"

Connected through hyperedge HE-2 (induced by source paper "evolution of statistical analysis in empirical software engineering research current state and steps forward"):
  with members:
    - "bayesian hierarchical modelling for tailoring metric thresholds"
    - "arguing practical significance in software engineering using bayesian data analysis"
    - "bayesian data analysis in empirical software engineering research"
    - "useful statistical methods for human factors research in software engineering a discussion on validation with quantitative data"
