Center node: "comprehensive indicator comparisons intelligible to non experts the case of two snip versions"
  Abstract: A framework is proposed for comparing different types of bibliometric indicators, introducing the notion of an Indicator Comparison Report. It provides a comprehensive overview of the main differences and similarities of indicators. The comparison shows both the strong points and the limitations of each of the indicators at stake, rather than over-promoting one indicator and ignoring the benefits of alternative constructs. It focuses on base notions, assumptions, and application contexts, which makes it more intelligible to non-experts. As an illustration, a comparison report is presented for the original and the modified SNIP (Source Normalized Impact per Paper) indicator of journal citation impact.
