Scope: The classification of researchers and scientists in Greece in a unified list based on the citation impact and dissemination level of their scientific work according to Google Scholar database

Classification criteria: First criterion is h-index. In the case of equal h-index, the following scientometric indicators are used for the classification. The number of total citations, the i10-index, the total impact factor of scientist, the m-index or m-quotient of scientist.

Information resource: The h-index, citations and i10-index derived from the public profiles of researchers in the Google Scholar database. In addition, the calculation of total impact factor and m-index of each researcher is carried out using the data from the Google Scholar database.

Methodology: Researchers and scientists accounts in the Google Scholar are detected by official domain names of institutions, universities and other organizations of public and private sector. The institution, university and organization of each researcher is defined by domain of email address that have been validated in the Google Scholar. In the next step, the values of h-index, citations and i10-index are recorded from profiles of researchers. If necessary, the total number of uploaded scientific articles and the dates of first published and last published article of researcher are recorded, these data are required for calculation of total impact factor and m-index of each researcher. In the final step, the classification of all researchers and scientist according to h-index and citations number, i10-index, impact factor and m-index is carried out.
