The journal impact factor is calculated on the average number of citations per paper published in that journal during the three preceding years.
Immediacy index based on the number of times articles published in the preceding year were cited in that year.
Eigenfactor Score, based on the number of citations received by articles in a journal, weighted by the rank of the journal the citations appear in.
Article Influence Score is a measure of the average influence of each of its articles over the first five years after publication.
Acceptance and circulation rates can be useful metrics in determining the relative importance of particular journals.
CiteScore is based on the average citations received per document. It is calculated on the number of citations received by a journal in on year to documents published in the three previous years, divided by teh number of documents indexed in Scopus published in those same three years.
Citation analysis is a way of measuring hte relative importance or impact of an author, an article, or a publication by counting the number of times that author, article, or publication has been cited by other works.
Why is citation analysis important? It provides answers to:
The h-iindex is based on the set of a researcher's cited papers and the number of citations that the researcher has received in other people's publications.
Example: If a researcher has 6 papers thave have been cited 6 or more times, their h-index is 6.
Three resources include the necessary citation data for h-index in their respective databases.
The h-index of an author will be different in each of these databases, since they calculate using their own journal content.
Alternative Metrics (Altmetrics) measure the impact of articles by counting mentions by social media sites and other web sources, not considered in traditional bibliometrics such as citation counts and impact factors. Altmetrics measure the impact of articles outside the means of traditional publishing, including
