human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "continuous dynamic and comprehensive article level evaluation of scientific literature"):
  Abstract: It is time to make changes to the current research evaluation system, which is built on the journal selection. In this study, we propose the idea of continuous, dynamic and comprehensive article-level-evaluation based on article-level-metrics. Different kinds of metrics are integrated into a comprehensive indicator, which could quantify both the academic and societal impact of the article. At different phases after the publication, the weights of different metrics are dynamically adjusted to mediate the long term and short term impact of the paper. Using the sample data, we make empirical study of the article-level-evaluation method.
