hindexek

The h-index is a metric used to measure the impact and productivity of a researcher's work. It was introduced by Jorge E. Hirsch in 2005. The h-index is defined as the largest number h such that the researcher has published h papers that have each been cited at least h times. For example, if a researcher has 10 papers, each of which has been cited at least 10 times, then the researcher's h-index is 10.

The h-index is often used to compare the productivity and impact of different researchers, particularly in fields where citation counts are high. However, it has been criticized for not taking into account the quality of the citations or the impact of the researcher's work outside of citations. Additionally, the h-index can be manipulated by researchers who publish a large number of low-quality papers with a few high-quality papers.

Despite these criticisms, the h-index remains a widely used metric in academia and is often included in databases such as Google Scholar and Web of Science. It is also used by some universities and research institutions to evaluate the performance of their faculty and researchers.
