1. Overview

The study “Greek scientific Publications 1996-2010: bibliometric analysis of Greek publications in international scientific journals” is the second part of a series of studies undertaken by EKT with an aim to record and analyze Greek scientific activity in the international landscape. The study relies on a range of data related with Greek Publications –such as the amount of publications, citations received, their distribution across scientific fields and institutions – to produce indicators which characterize the country’s research activity, describe progress and allow for further correlations with activity at EU and international level.

Bibliometric indicators provide significant information and contribute to a measurable and objective picture of the Research & Development systems. They are commonly used measures of research activity and performance in institutions, research centers, research groups or individual researchers. Moreover, they provide information about research activity across scientific fields, point to the emergence of new subject areas and map research networks created for the achievement of common scientific goals.

Bibliometric indicators are a valuable tool and form part of a broader system of indicators for the evaluation of research activity. It is a fact that an amount of published articles point to certain limitations of bibliometric analyses (e.g. differences in publications practices and citations across scientific fields such as for example the differences observed between the fields of medicine and humanities). However, these limitations can be overcome when bibliometric indicators are interpreted in the right contextual framework, taking into account additional data and statistics but also qualitative research outcomes.

The National Documentation Center (EKT) has applied a robust methodological approach and validation techniques in bibliometrics. It has also developed software tools which enabled the processing of data collected and the calculation of bibliometric indicators (data cleaning, processing and normalisation, distribution of publications across scientific fields and subfields, graphic representation).

The current study recorded the country’s output in scientific publications and its performance during a period of fifteen years (1996-2010). To highlight recent trends and progressions, there is a special focus on data of the last five years of the period. The analysis was based on the methodological framework (e.g. databases, range of indicators, method of calculations, range of institutions and scientific fields) followed in the previous study published by EKT two years ago, so as to ensure consistency of calculations and results.

The indicators present the number and share (%) of publications, percentage (%) of cited publications, number and share (%) of citations, citation impact, field normalised citation score, number and percentile breakdown of the highly cited publications.

The following paragraphs summarise findings regarding the total output and performance of Greek publications, the main institution categories in which scientific activity is distributed, scientific fields with the greatest share of publications, scientific collaborations etc. Readers may find detailed information about data and figures throughout the chapters and read about the study’s methodological approach in Annex I.
