Indicadores Bibliométricos
Para a constituição dos indicadores bibliométricos foram considerados
exclusivamente artigos e revisõespublicados entre 2007 e 2010 e incluídos em
Science Citation Index Expanded (SCI-EXPANDED), Social Sciences
Citation Index (SSCI), Arts & Humanities Citation Index
(A&HCI).
Indicadores Bibliométricos CWTS:
-
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%) – Percentage of highly cited publications.
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.
-
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.
