Felix de Moya Anegon. This post is devoted to characterize the research activity carried out at Spanish Higher Education Institutions over the period 2006-2010. The following table (in PDF format) shows scientometric indicators of research output, international collaboration, normalized impact, % Output in 1st quartile journals according to the Scimago Journal Rank indicator and the number of works of excellence (ordering criteria) published by any of the institutions.
The indicators exposed are the following:
The output or number of scientific papers published in scholarly journals reveals the ability of an institution to produce scientific knowledge. Output values are affected by institution sizes and research profiles, among others factors. The Output indicator forms the basis for more complex metrics. At co-authored publications a score is assigned to each contributing institution through the author’s institutional address.
This indicator shows the ability of institutions to create international research links through the output ratio that has been produced in collaboration with foreign institutions. The values are computed by analyzing the institution’s output whose affiliations include more than one country address.
Normalized Impact scores indicate the scientific impact that institutions have over the scientific community. In order to obtain a fair measurement of such impact, its calculation removes the influence due to institutions’ size and research profile making it ideal for comparing research performance. Normalized Impact values show the ratio between the average scientific impact of an institution and the world average impact of publications of the same time frame, document type and subject category. The values are expressed in percentages and show the relationship of the institution’s average impact to the world average, which is 1, –i.e. a score of 0.8 means the institution is cited 20% below world average and 1.3 means the institution is cited 30% above world average. Normalized Impact is computed using the methodology established by the Karolinska Intitutet in Sweden where it is named “Item oriented field normalized citation score average”. The long name used is because the normalization of the citation values is done on an individual article level.

High Quality Publications Q1
Ratio of publications an institution publishes in the world most influential scholarly journals. Journals considered for this indicator are those ranked in the first quartile (25%) in their categories as ordered by SCImago Journal Rank SJR indicator.
The Excellence indicates the number of papers an institution included into the set formed by the 10% of the most cited papers in their respective scientific fields. It is a measure of high quality output of research institutions.
