Methodological notes

Data was drawn from the National Science Indicators [NSI] and the National Citation Report Greece [NCR-Greece] databases of Thomson Reuters for the period 1993-2008.

A software was developed by EKT specifically for the statistical processing of the data and the calculations of the bibliometric indicators.

Calculations were based on those types of papers that contain substantive scientific information, namely, articles, research notes and reviews.

Normalization is always applied when assessing the impact of publications to smooth out differences in citation practices in various scientific fields.

The 'whole counting' technique was adopted, e.g. each co authored publication is counted once for each organisation


A most challenging issue: the assignment of Greek publications to relevant Greek organisations

Varying methods of naming organisations and making data entries and almost general use of abbreviations and abridgements. Some typical cases are: Incorrect typing or spelling [eg Aristetelio Univ Thessaloniki].

Inconsistent use of abbreviations, abridgements and initialing [eg Polyclin and Polycliniki, NTUA and Natl Tech Uni Athens].

Variability of transliteration of Greek names into Latin characters [eg Natl & Capodistrian Univ Athens and Natl & Kapodistrian Univ Athens]

Permutation of words [eg Natl Tech Univ Athens and Athens Natl Tech univ].

Use of 'Greeklish' instead of foreign language names [eg Ethniko Metsovio Polytech and Nat Tech Univ Athens].

Use of the name of the smaller unit [eg institute, department , laboratory] with or without reference to the parent organisation [eg Dept Chem Eng].

Use of incomplete names which do not identify the organisation in one way [eg Tech Educ Inst, Gen Hosp, Uni Hosp].

Existence of postal address only, without a name reference.


A revised version of the database was produced

Steps of the process:I. Alternative names for each organisation, as they were recorded

from previous activities of EKT, were accumulated, recorded in a suitable way for automatic processing and elaborated with new details.

II. Improvement in the quality of data resulting from step 1, through the use of software designed for automatic duplicate detection. For the automatic processing, 'clustering' was used and the necessary tools were developed.

III. Manual corrections to the results of the above mentioned automatic procedure.

IV. Production of a new edition of the database with the replacement of all the alternative names per organisation with only one valid written representation.

Major Greek Actors in the Production of Publications

The Greek organizations were grouped into 11 categories based on the type of activity and their status as public or private institutions.

The following 6 categories participate in 97% of Greek publications:

Higher Education

1. Universities

2. Technological Educational Institutes [TEI]

Research

3. Research Centres supervised by the General Secretariat of Research and Technology [GSRT]

4. Other Public Research Centres

Health5. Public Health Bodies

6. Private Health Bodies

Other categories with a much smaller but still identifiable share are: Organizations supervised by the Ministry of Defence, Banks, Museums, Other Public Organizations and Other Private Organizations.

Scientific Fields of Greek Publications

• Greek scientific publications were divided into the six major fields and their subcategories, as suggested by the Revised Field of Science and Technology Classification in the Frascati manual / OECD.

• The classification was based on data from the last 5-year period, 2004-2008, in order to record emerging scientific areas of significant research interest.
