Bibliometric analysis for the period 1996-2010, with elements of the international database Scopus & interactive maps
for each Greek region  




The new study of the National Documentation Center (ECB) “Greek Scientific Publications 1996-2010: Bibliometric analysis of Greek publications in international scientific journals - Scopus”Is availablenlineto the address www.ect.gr/metrics/carry-over03. The study reflects the scientific work of Greek actors in international journals for the fifteen-year period 1996-2010 and highlights the position that Greece occupies in the international environment.

Still, aiming to better illustrate and highlight the regional dimension of Greek scientific and research activity, the ESF has mapped in its interactive maps the main bibliometric indicators in each Greek region (http: //metrics.ect.gr/map-diagrams).

The new study, based on data from the Scopus international bibliographic database, is the third in a series of studies (www.ect.gr/metrics) established by the ESF in order to provide a reliable basis for presenting and monitoring the evolution of the elements that determine the research environment of Greece compared to that of the EU and OECD countries.

By presenting indicators derived from the two established international databases (Web of Science of Thomsonto Reuters: the two previous studies, and Scopus of E.lsevier: current version), the ESF gives a fuller picture of important indicators that characterize the current reality as well as the evolution of scientific production in the country and broadens the number of Greek publications and the scientific fields covered. Thus, the well-established bibliometric indices reflecting the current reality of Greek research activity are being defined in a way that can be exploited at the level of policy-making, research, technological development and innovation.

According to the results of the study, Scopus data confirm that during the period 1996-2010, Greek publications are dynamically placed in the international environment in terms of impact, originality, quality and awareness. Global indicators and Greece's position in the EU, the OECD and internationally upgraded, the impact of publications is increasing and the performances of the agencies are improving. The number of reports in Greek publications, which is the basis for calculating bibliometric indices, continues to increase.

Characteristically it is reported that as shown by the data of the base Scopus, in the five years 2006-2010, Greek publications with 4,98 citations per publication exceed the average OECD citations (4,79). Also, it has a high impact in all scientific fields, with the highest impact in the field "Humanities" (relative impact index: 1,14 with global average 1), followed by the fields "Engineering & Technology" (1,12) , "Agricultural Sciences" (0,99), "Natural Sciences" (0,97), "Medicine & Health Sciences" (0,93) and "Social Sciences" (0,81).

The study includes analytical data for 95 entities grouped into 8 categories (Universities, TEIs, Research Centers supervised by the General Secretariat for Research and Technology, Other Public Research Institutions, Public Health Bodies, Private Health Bodies, Other Public Institutions and Other Private Entities ).

The interactive maps present data on the scientific output of each region, as evidenced by the number of scientific publications produced by the institutions that are based on it, the impact on the international level (number of reports and relevant impact index) and the scientific fields"Natural Sciences", "Engineering & Technology", "Medicine & Health Sciences", "Agricultural Sciences", "Social Sciences" and "Humanities") covered in each region.

Maps are continuously enriched, including additional indicators reflecting regional research dynamics, such as participation in European works by 7th Framework Program for EU research to present a full picture of regional excellence and competitiveness.

The development of the online environment for the electronic version of the study was carried out in the context of the operation "National Information System of Research and Technology / Social Networks - Content Produced by Users" (www.epset.gr) implemented by the ESF in the framework of the Operational Program "Digital Convergence" (NSRF 2007-2013), co-financed by Greece and the European Union-European Regional Development Fund.

For the statistical processing of data and the calculation of reliable bibliometric indicators, the ESF has developed a specialized software, methodological approach and control techniques. For the presentation of the results, the electronic version, which includes interactive diagrams, with multiple possibilities for presentation and adaptation to the readers' needs was chosen. It also provides the opportunity for feedback from readers to contribute to a creative dialogue on research in Greece. The study is also available in English.

The results of the study

The number of Greek scientific publications has risen steadily to 2009, at rates significantly higher than those of the European Union and the OECD. 2010, this steady upward trend is halted, and Greece records a negative change rate. Based on 2010 data, Greece participates in 2,4% of EU scientific publications and 0,85% of the OECD, significantly increasing 1996 shares.

As for the number of petitions, Greece also has higher growth rates than the EU and OECD countries throughout the 1996-2010 period. In the five-year period 2006-2010, Greek publications received 277.130 reports, almost five times the 1996-2010 period. 

In the five-year period 2006-2010, Greek publications receive an average of 4,98 reports per publication, exceeding the OECD average (4,79), while in the EU the average of reports per publication is 5,52. In the five-year period 1996-2000 the average of reports in Greek publications was just 2,45.

The relative magnitude of Greek publications continues its upward trend throughout the 1996-2010 period, and with the 1,04 value being the same as the average of the OECD countries, it is set at 0,90 in relation to the EU.

Improved are also the other indicators measured in the study and related to the recognition of Greek scientists and the impact of their research work on the international community. In the five-year period 2006-2010, the percentage of publications receiving references (% cited publications) for Greek publications is set to 65,6%.


Who produces the most scientific publications

The three most important categories of Greek institutions in terms of number of publications are Universities, Public Health Bodies and Research Centers supervised by the General Secretariat for Research and Technology (GSRT). Followed by TEIs, Other Public Research Institutions, Private Health Bodies, Other Private and, finally, Other Public Institutions.

In the five-year period 2006-2010 the participation of Universities in all Greek publications is 79% (43.960 publications), Public Health Institutions 14,3% (7.933 publications), GSRT Research Centers 12%, (6.675 publications), TEI 5,2% (2.868 publications), Other Public Research Organizations 3,3% (1.862 Publications), Private Health Organizations 2,6% (1.441 Publications), Other Private Institutions 2,3% (1.291 Publications) and Other Public Organizations 1,7% (942 publications).  

The highest reporting rates are achieved  GSRT Research Centers and Private Health Bodies, with 75% and 69,5% respectively in the five-year 2006-2010. In addition, publications from the Research Centers supervised by the GSRT and the Private Health Bodies, with relevant impact indicators 1,20 and 1,18 respectively, are more successful than the global average.

What scientific fields dominate

To capture research activity in scientific fields  The six main scientific fields were used: Natural Sciences, Engineering & Technology, Medicine & Health Sciences, Agricultural Sciences, Social Sciences and Humanities (Humanities) as well as their subcategories, according to the relevant manual Frascatithe OECD.  

For 2010 most Greek publications (53,4%) are classified in the scientific field "Natural Sciences" followed by the fields "Medicine & Health Sciences" (42%), "Engineering & Technology" (23,1%), Social Sciences ”(10,7%),“ Agricultural Sciences ”(5,1%) and“ Humanities ”(1,7%).

In the five years 2006-2010, the relevant ratings of Greek publications in the main scientific fields are improving. The highest impact (relative impact index: 1,14) is recorded in the field "Humanities", followed by the fields "Engineering & Technology" (1,12), "Agricultural Sciences" (0,99), "Natural Sciences" ( 0,97), "Medicine & Health Sciences" (0,93) and "Social Sciences" (0,81).

Regarding the categories of bodies that show high performance in each scientific field, they are distinguished: in the scientific field "Natural Sciences" the Research Centers of GSRT (relative impact index 1,11), in the field "Engineering & Technology" the Research Centers of GSRT (1,25) and the publications of the Universities (1,13), in the field “Medicine & Health Sciences” the Research Centers of the GSRT (1,22), the Private Health Bodies (1,17) and the Other Public Research Bodies (1,03), in the field "Agricultural Sciences" the Research Centers of GSRT (1,06) and the Universities (1,05), in the field "Social Sciences" the Research Centers of GSRT (1,11) and in the field "Humanities" the Research Centers of the GSRT (2,55) and the Universities (1,04).

With whom the Greek researchers work together

During the fifteen-year period of 1996-2010, there is a large increase in the percentage of publications made in cooperation with either Greek or foreign bodies. 2010 62,3% of Greek publications is a product of collaboration, while 1996 was 51,5%. In particular, 39,5% of Greek publications are produced with the collaboration of overseas agencies, while 32,1% is made through collaborations between Greek entities.

Throughout 1996-2010, there has been a significant increase in collaborations between Greek entities, a potential result of funding of national consortia for the implementation of research projects. The number of collaborations with the international research community is also increasing, albeit at a slower pace than the Greek partnerships.

Over the past five years 2006-2010, Greek scientists have collaborated with scientists from 166 countries around the world. The largest number of collaborations is with the United States, the United Kingdom, Germany, France and Italy.
