Assessing Journal Quality

The Eigenfactor Score calculation is based on the number of times articles from the journal published in the past five years have been cited in the JCR year, but it also considers which journals have contributed these citations so that highly cited journals will influence the network more than lesser cited journals.

SCImago Journal Rank (SJR indicator) is a measure of scientific influence of scholarly journals contained in the Scopus® database from 1996. The main difference between SJR and the Impact Factor is that the IF gives equal weight to all citations, making no distinction between citations published in some obscure journals and citations published in Nature or Lancet. To address this issue, SJR uses mathematical approach behind the Google's PageRank algorithm and adapts it to journal metrics. The PageRank model type weights citations from journals according to how highly cited the journal is itself.

ALMs are quantifiable measures that document the many ways in which both scientists and the general public engage with published research. Traditional metrics, which consider only citation count and journal name to assess impact, capture a narrow view of a work’s value and do so only after the accumulation of citations in academic literature.

Google Scholar Metrics provide an easy way for authors to quickly gauge the visibility and influence of recent articles in scholarly publications. Scholar Metrics summarize recent citations to many publications, to help authors as they consider where to publish their new research.
