The reports produced by the Bibliometric Office consider various impact and journal indicators, at the level of individual authors, institution, Scientific Disciplinary Sector (SSD), and the relevant CUN (National University Council) area. Below, we list the main ones with their respective descriptions.
Scopus/SciVal Impact Metrics
Number of Citations (with and without self-citations)
Views Count e Field Weighted Views Impact
Field Weighted Citation Impact (FWCI): the number of Scopus citations normalized for the age, type, and subject category of the originating journal.
Field Citation Average (FCA): the average (expected) number of Scopus citations received by articles of the same type published in the same year in journals assigned to the same subject category.
Outputs in top citation percentiles, per percentile: percentile rank of the Scopus citation count (non-normalized) compared to the citations received by all articles of the same year indexed in Scopus.
Field weighted outputs in top citation percentiles, per percentile: percentile rank of the Scopus citation count, normalized as FWCI, compared to the citations, in turn normalized as FWCI, received by all articles indexed in Scopus.
WoS/InCites Impact Metrics
Number of Citations (with and without self-citations)
Usage Count
Category Expected Citations: the average (expected) number of WoS citations received by articles of the same type published in the same year in journals assigned to the same subject category.
Journal Expected Citations: the average (expected) number of WoS citations received by all articles of the same type published in the same journal in the same year.
Category Normalized Citation Impact: the number of WoS citations normalized for the age, type, and subject category of the originating journal.
Journal Normalized Citation Impact: numero citazioni WoS normalizzato per età , tipologia e rivista di provenienza.
Percentile in subject area: percentile rank of the WoS citation count compared to the citations received by all similar articles in terms of age, type, and subject category.
Scopus/SciVal Prestige Metrics
CiteScore: an impact indicator for the journal in the year of publication of the corresponding article.
CiteScore best percentile: percentile rank of the CiteScore within the Scopus category where it performs the best.
Scimago Journal Ranking (SJR): a prestige indicator for the journal in the year of publication of the corresponding article.
SJR best percentile: percentile rank of the SJR within the Scopus category where it achieves the highest ranking.
Source Normalized Impact per Paper (SNIP): an impact indicator for the journal in the year of publication of the corresponding article.
SNIP best percentile: percentile rank of the SNIP within the Scopus category where it has the best placement.
WoS/InCites Prestige Metrics
Impact Factor ISI (IF): an impact indicator for the journal calculated in the year of publication of the corresponding article.
IF best percentile: percentile rank of the Impact Factor ISI within the Web of Science (WoS) category where it achieves the highest placement.
