Journal Citation Reports (JCR) is an annual publication by Clarivate. [1] It has been integrated with the Web of Science and is accessed from the Web of Science Core Collection. It provides information about academic journals in the natural and social sciences, including impact factors. JCR was originally published as a part of the Science ...
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
The journal is abstracted and indexed in Scopus and the Science Citation Index Expanded.According to the Journal Citation Reports, its 2017 impact factor is 1.579, ranking it 36th out of 61 journals in the category "Automation & Control Systems" [1] and 32nd out of 61 journals in the category "Instruments & Instrumentation".
For instance, most papers in Nature (impact factor 38.1, 2016) were only cited 10 or 20 times during the reference year (see figure). Journals with a lower impact (e.g. PLOS ONE, impact factor 3.1) publish many papers that are cited 0 to 5 times but few highly cited articles. [21]
The journal publishes the complete scientific documentation of the CERN Large Hadron Collider machine and detectors.These papers are published as open access. [6] It also publishes the technical reports concerning the Planck Low Frequency Instrument on board the European Space Agency's Planck satellite, which was launched in May 2009, and the three-volume technical report of the Deep ...
This is a list of open-access journals by field. The list contains notable journals which have a policy of full open access. It does not include delayed open access journals, hybrid open access journals, or related collections or indexing services.
Author-level metrics are citation metrics that measure the bibliometric impact of individual authors, researchers, academics, and scholars. Many metrics have been developed that take into account varying numbers of factors (from only considering the total number of citations, to looking at their distribution across papers or journals using statistical or graph-theoretic principles).
The values for Nature journals lie well above the expected ca. 1:1 linear dependence because those journals contain a significant fraction of editorials. CiteScore was designed to compete with the two-year JCR impact factor, which is currently the most widely used journal metric. [7] [8] Their main differences are as follows: [9]
