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. Furthermore, it provides rankings of institutions based on the scientific characteristics of affiliated scientists.

This new index has been developed by Prof. Dr. Murat ALPER (MD) and Associate Prof. Dr. Cihan DÖĞER (MD) by using the total and last 5 years’ values of the i10 index, h-index, and citation scores in Google Scholar.  In addition, the ratio of the last 5 years’ value to the total value of the abovementioned indexes is used. Using a total of nine parameters, the “AD Scientific Index” shows the ranking of an individual scientist by 12 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, 13,542 institution, 206 country, 11 region (Africa, Asia, Europe, North America, South America, Oceania, Arab Leageu, EECA, BRICS, Latin America and COMESA) and in the world. The “AD Scientific Index” is the first and only study that shows the total and the last five-year productivity coefficients of scientists based on the h-index and i10 index scores and citations in Google Scholar. In other words, the “AD Scientific Index” provides both the academic ranking and analysis results.

One of the major differences of the AD Scientific Index is the provision of the last five years’ scores and the total scores of the h-index and the i10 index, and the total and last five 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. Productivity Rankings is an instrument that lists productive scientists in a given area, discipline, university, and country and can guide the development of meaningful incentives and academic policies. The world rankings, regional rankings, and university rankings of scientists in this table are developed based on the total i10 index. Thus, scientists and universities can obtain their academic rankings and monitor developments in the ranking over time.

Through the contribution of many scientists from different fields, the "AD Scientific Index" undergoes systematic updates with the aim of continuous improvement. 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.
