Abstract

Background and Objectives: In the current age, due to the increasing growth of knowledge and competition therein, evaluation of scientific products by means of scientometric methods has become a very important and necessary subject. Scientometrics, in simple words, is the science of measuring the knowledge. Scientometric indices are divided into three categories: productivity metrics that measure the productivity of the researchers or research groups, impact metrics that assess the quality (or performance) of journals, researchers, or research groups, and hybrid metrics that are used to summarize both productivity and effect metrics in one index. Scientometric studies help policy makers and managers of universities and heads of research centers in allocating budget, creating a balance between the budget and costs, making appointments, and promoting the researchers and institutes, and results in better recognition of weaknesses and strengths of their affiliated groups by evaluation of priorities, perspectives, and capacities. Meanwhile, this new knowledge can help with systematic evaluation and ranking of universities and research centers. This paper provides a review on scientometric concepts and its applications and discussed scientometric indices. © 2015, Iranian Journal of Epidemiology. All right reserved.
