An acknowledgment index
is an experimental method for analyzing the scientific literature
; it quantifies the acknowledgments
in scientific journals. Typically, such an article has a section where the authors acknowledge funding, technical staff, and colleagues that have contributed materials or knowledge. Like the citation index
it measures influences on scientific work, but in a different sense; it measures institutional and economic influences as well as informal influences of individual people.
Unlike impact factor
, it does not produce a single overall metric, but analyses the components separately.
