Center node: "socializing the h index"
  Abstract: A variety of bibliometric measures have been proposed to quantify the impact of researchers and their work. The h-index is a notable and widely-used example which aims to improve over simple metrics such as raw counts of papers or citations. However, a limitation of this measure is that it considers authors in isolation and does not account for contributions through a collaborative team. To address this, we propose a natural variant that we dub the Social h-index. The idea is to redistribute the h-index score to reflect an individual's impact on the research community. In addition to describing this new measure, we provide examples, discuss its properties, and contrast with other measures.

Connected through hyperedge HE-1 (induced by source paper "h index and its alternative a review"):
  with members:
    - "restricting the h index to a publication and citation time window a case study of a timed hirsch index"
    - "a variant of the h index to measure recent performance"
    - "a review of the characteristics of 108 author level bibliometric indicators"
    - "impact vitality a measure for excellent scientists"
    - "simple arithmetic versus intuitive understanding the case of the impact factor"
    - "central indexes to the citation distribution a complement to the h index"
    - "the inconsistency of the h index"
    - "weighted indices for evaluating the quality of research with multiple authorship"

Connected through hyperedge HE-2 (induced by source paper "bibliometric index for academic leadership"):
  with members:
    - "some variations on the standard theoretical models for the h index a comparative analysis"
    - "comparison of the h index for different fields of research using bootstrap methodology"
    - "predicting results of the research excellence framework using departmental h index revisited"
    - "the academic trace of the performance matrix a mathematical synthesis of the h index and the integrated impact indicator i3"
