Journal metrics
Journal metrics are indicators that measure the impact, influence, and prestige of journals. These metrics make it possible to assess the relevance of a journal within the academic community and compare it with other publications. In Scopus, there are several journal metrics that help measure the quality and influence of publications:
- CiteScore™ metrics: introduced in 2016, this is a set of eight indicators for analysing the influence of serial publications. CiteScore metrics offer more robust, timely, and accurate indicators of the impact of a serialised title.
- SCImago Journal Rank (SJR): a prestige metric for journals, book series, and conference proceedings, which weights the value of a citation based on the subject area, quality, and reputation of the source.
- Source-Normalised Impact per Paper (SNIP): measures the contextual impact of citations, taking into account differences in disciplinary characteristics. It is useful for comparing journals in different areas.
Example:
You can compare up to 10 journals and review the results in a graph or table format.
Paper metrics
Paper metrics are indicators used to measure the impact and visibility of specific scientific publications, such as research papers. These metrics help assess the influence of a paper within the academic community and its relevance in a particular area of study.
On Scopus, you can find specific metrics such as:
- Total number of citations: the total number of citations received within a date range chosen by the user.
- Citations per year: the number of citations received per year, within a given interval.
- PlumX Metrics: offer insights into how people interact online with different research outputs, such as papers and book chapters. These metrics are divided into five categories:
- Citations: traditional indexes and citations that indicate social impact.
- Usage: frequency of reading and use of papers, which is relevant for researchers.
- Captures: indicates interest in returning to the work, and can signal future citations.
- Mentions: measures coverage in news and blogs, thus reflecting public involvement.
- Social media: references on platforms such as Twitter and Facebook, which helps to measure impact.
The categories are represented separately, as each of them reflects a different type of involvement. They are visualised using Plum Print, where coloured circles indicate the number of metrics in each category. The larger the circle, the more metrics are associated.
Author metrics
Author metrics are indicators used to assess the performance and impact of a researcher or author throughout their academic career. These metrics provide information on the author's scientific output, enabling a more in-depth analysis of their contribution to the academic community.
The available author metrics include:
-
h-index and h-graph: which evaluate a researcher's performance based on publications throughout their career, measured by the total number of citations each paper receives over time. This metric depends on both the quantity (number of publications) and quality (number of citations) of academic publications.
-
Citation overview tracker: an adjustable table that includes the number of times each document has been cited, by year of publication.
-
Author output analysis: a collection of detailed, visual analysis tools that is designed to provide a better view of an author's publication history and influence.
