# Bibliometric Trends in Industry 5.0 Research: An Updated Overview
## 4 Citation-Based Analysis of Industry 5.0 Research
### Most Impactful Authors  
An overview of the 25 most influential authors who have made significant contributions to the scientific literature on I5.0 is presented in Table 6. The table lists various metrics for these researchers: h-index, total citations (TC), number of articles published (NP) and start year. The h-index is a measure of a researcher's productivity and impact. H-index is defined as the highest number h such that h of a researcher's papers have at least h citations each. TC represents the total number of citations for a particular researcher, NP represents the number of papers that a researcher has published, whereas start year represents the year the researcher started publishing on I5.0.
