We found that the most salient distinction is made by PC1 which separates usage from citation measures with the exception of Citation Betweenness centrality and Citation Immediacy.
The reliance on citation-based measures, from the Hirsch index (4) to the g-index (11), from impact factors (1) to eigenfactors (12), and on diverse ranking-based metrics (13) lies in the (often debated) perception that citations offer a quantitative proxy of a discovery's importance or a scientist's standing in the research community.
Name of validated measure (items amended or partially sourced from existing measures indicated by citation only) For period from recruitment or birth until 24 months (mother and child); Primary outcome domain.
Instead of measuring co-citations between traditionally defined fields, Rosvall and Bergstrom (2007) define the boundaries of disciplines empirically from citation patterns.
JIF is based on information obtained from citation indexes.
An indication of this comes from citation analysis.
From citation you found by the commentators: Check the sources of citations.
We retrieved the following 4 measures from its web site: (Table 1, ID 1) The citation PageRank of a journal calculated on the basis of Elsevier Scopus citation data divided by the number of articles published by the journal in the citation period (3 years) (http://www.scimagojr.com/SCImagoJournalRank.pdf), i.e. an average per-article journal PageRank.
Our findings have policy implications, because current measures of citation-based impact, from IF to Hirsch index (4, 17), are frequently integrated in reward procedures, the assignment of research grants, awards, and even salaries and bonuses (30), despite their well-known lack of predictive power.
However, the quality of obesity research from Arab countries was not higher than that produced from neighboring non-Arab countries as measured by citation analysis.
