“AD Scientific Index” (Alper-Doger Scientific Index):

The AD Scientific Index (Alper-Doger Scientific Index), unlike other systems that provide evaluations of journals and universities, is a ranking and analysis system based on the scientific performance and the added value of the scientific productivity of individual scientists. This new index has been developed in 2021 by Prof. Dr. Murat ALPER (MD) and Associate Prof. Dr. Cihan DÖĞER (MD) by using the total and last 6 years’ values of the i10 index, h-index, and citation scores in Google Scholar. Using a total of nine parameters, the “AD Scientific Index” shows the ranking of scientists by 11 subject (Agriculture & Forestry, Arts, Design and Architecture, Business & Management, Economics & Econometrics, Education, Engineering & Technology, History, Philosophy, Theology, Law / Law and Legal Studies, Medical and Health Sciences, Natural Sciences, Social Sciences and Others), 256 branch, 22,350 institution, 218 country, 10 region (Africa, Asia, Europe, North America, Oceania, Arab Leageu, EECA, BRICS, Latin America and COMESA) and in the world. 

AD Scientific Index "World Scientist and University Rankings" has a distinctive methodology that includes the most useful academic analyses for yourself, your institution, your country and your subject that you will not find elsewhere.  The “AD Scientific Index” is the first and only study that shows the total and the last six-year productivity coefficients of scientists based on the h-index and i10 index scores and citations in Google Scholar. Such analyses also help reveal the medium and long-term results of several policies implemented by institutions, including those of the academic staff employment and retention policies, wage policies, academic incentives, and scientific working environments. Besides the indexing and ranking functions, AD Scientific Index sheds life on academic lives and offers the user the opportunity to perform an efficient academic analysis to scrutinize and detect faulty and unethical profiles, plagiarism, forgery, distortion, duplications, fabrication, slicing, salamization, unfair authorship, and several manifestations of academic mobbing.

One of the major differences of the AD Scientific Index is the provision of the last six years’ scores and the total scores of the h-index and the i10 index, and the total and last six years’ number of citations. Other unique differences of the AD Scientific Index include rankings in all fields and subjects of scientific interest and the emphasis on the scientific productivity of the scientist. Productivity Rankings is a unique service offered only by “AD Scientific Index”. This is a ranking system derived from the i10 index in order to show the productivity of the scientist in publishing scientific articles of value.

AD Scientific Index University / Institute Rankings performs rankings using a single parameter, which is the number of "Valued and Productive Scientists". Selected after years of observation, this parameter is calculated using the total H-index and i10-index values together with the number of citations, and the last 6 years’ total H-index and i10-index values along with the number of citations received over the last 6 years. We rank more than 21.600 universities using this method. A careful examination will reveal that most of the other parameters are representations of natural academic products of "Valued and Productive Scientists." Institutions that employ a high number of "Valued and Productive Scientists", for example, scientists in the first Top 3%, Top 10%, Top 20%, Top 40%, Top 60%, Top 80% and later ranks, respectively, will naturally produce increased numbers of academic outputs listed as the parameters above.

A comparison of "AD Scientific Index" scores of universities, some examples of which are given below, with the scores from other ranking institutions will show great agreement among scores. We use our methodology to rank universities of different characteristics and sizes from different countries and every continent, achieving very successful results through the yielded ranking figures. Considering the continuing processes of data entry and data cleaning for more than 22.350 universities, we foresee that data entry issues, such as not completed entries or human errors in data entry caused either by universities or our team mistakenly, will be resolved and will yield to improved accuracy of results over time.

Fee Policy: The index is an independent institution and does not receive any support from any institutions, organizations, countries, or funds. Concurrently with the continuous increase in the number of universities and scientists registered to the Index, we are improving methodology, software, data accuracy, and data cleaning procedures every day through the contributions of a large team. Your remarks and contributions about our shortcomings will shed light to lead our efforts for continuous improvement.
