English answer:
Q1: What is the Scimago Journal & Country Rank (SJR)?
A1: The Scimago Journal & Country Rank (SJR) is a
prestigious ranking system that evaluates the scientific
impact of journals and countries. It is developed by the
Spanish National Research Council (CSIC).
Q2: What are the criteria used to calculate the SJR?
A2: The SJR is calculated based on the following
criteria:
Citation Impact: The average number of citations
received by articles published in the journal.
Prestige: The prestige of the journal, as determined
by the number of citations received by articles published in high-impact journals.
Collaboration: The level of collaboration among
authors who publish in the journal.
International Impact: The percentage of citations
received from international sources.
Q3: How is the SJR presented?
A3: The SJR is presented in the form of a table, with
journals and countries ranked according to their SJR scores.
The table is divided into four quartiles, with Q1 being the
highest quartile and Q4 being the lowest quartile.
Q4: What is the relationship between the SJR and the
Journal Impact Factor (JIF)?
A4: The SJR and the JIF are two different metrics used
to evaluate the impact of journals. While the JIF focuses
on the number of citations received by articles in a
journal over a two-year period, the SJR takes into account a wider range of factors, including the prestige of the
journal and the international impact of its articles.
Q5: What are the advantages of using the SJR?
A5: The SJR has several advantages over the JIF,
including:
It provides a more comprehensive assessment of the
impact of journals.
It is not as susceptible to manipulation as the JIF.
It is more transparent than the JIF.
