The nature of performing a scientific research is a process that has several different 
components which consist of identifying the key research question(s), choices of scientific 
approach for the study and data collection, data analysis, and finally reporting on results. 
Generally, peer review is a series of procedures in the evaluation of a creative work or 
performance by other people, who work in the same or related field, with the aim of 
maintaining and improving the quality of work or performance in that field. The assessment 
of the achievement of every scientist, and thus indirectly determining his reputation in the 
scientific community of these publications, especially journals, is done through the so‑called 
impact factor index. The impact factor predicts or estimates that how many annual citations 
article may receive after its publication. Evaluation of scientific productivity and assessment 
of the published articles of researchers and scientists can be made through the so‑called 
H‑index. The quality of published results of scientific work largely depends on knowledge 
sources that are used in the preparation, which means that it should be considered to serve 
the purpose and the very relevance of the information used. Scientometrics as a field of 
science covers all aforementioned issues, and scientometric analysis is obligatory for quality 
assessment of the scientific validity of published articles and other type of publications.
