Bibliometry

Bibliometric Indicators

Bibliometric indicators were applied only to articles and reviews published between 2007 and 2010 and included in Science Citation Index Expanded (SCI-EXPANDED), Social Sciences Citation Index (SSCI), Arts & Humanities Citation Index (A&HCI).

CWTS bibliometric indicators:

• P – Number of publications in international journals of the unit of analysis in the entire period;
• TCS – Number of citations received by P during the entire period, excluding self-citations;
• MCS – Average number of citations without self citations per paper;
• PP (uncited) – Percentage of publications not cited by others (in the given time period);
• MNCS – Mean field normalized citation score. This is the actual number of citations (without self citations) divided by the expected number of citations on a paper basis.  The expected number of citations is based on the world-wide average citation score without self-citations of all similar papers belonging to the same field (journal subject category).  In this way, a field normalized score is calculated for each paper.  Next, the MNCS indicator is computed for the unit of analysis by taking the average of these field-normalized citation scores for individual papers.  A value above 1 indicates that the mean impact for the unit is above world average whereas a value below 1 indicates the opposite.
• MNJS – Mean normalized journal score. Indicates the average citation impact of the journals that are used by the unit and is calculated based on the same principles as the MNCS.  The indicator shows whether the unit publishes in top or in sub-top journals.
• PP (top10%) – Proportion of publications belonging to the top 10% most frequently cited publications in a field (self-citations not included) 
• TNCS – Total field normalized citation score;
• Coverage – Internal coverage. Measured by the proportion of cited references in the oeuvre linking to other WoS publications;
• PP (collab) – Publications that are done in institutional collaboration (the shares are calculated based on the total number of publications);
• PP (int collab) – Publications that are perfomed among institutions of more than one country (the shares are calculated based on the total number of publications);
     "no collaboration" - Publications from a single FCT institute;
     "national collaboration" - Publications from at least two authors in the same country (Portugal);
     "international collaboration" - Publication from FCT funded institutes with one or more foreign (non-Portuguese) institutions.
