摘要

Researchers play an essential role in expanding the boundaries of knowledge through rigorous investigations and the dissemination of their findings in research publications. These publications are often used as an indicator to evaluate a researcher’s scholarly impact. Researchers ranking indices, including the number of publications, citations, co-authors, and h-index, are used to evaluate a researcher's productivity and impact. Although the h-index is widely regarded as a primary indicator of research impact, its limitations have prompted the development of alternative variants. However, there is no consensus within the academic community on the most effective ranking index, as most recent studies have either used limited data or relied on hypothetical scenarios to assess their importance. Our study compares the effectiveness of the h-index and its variants in identifying exceptional researchers within a specific field. We have compiled an extensive dataset derived from the field of Civil Engineering. For evaluating the results of indices, awardees from four distinct Civil Engineering awarding societies serve as benchmarks. We assess the performance of these indices, particularly in distinguishing exceptional researchers. Firstly, we examine the correlation between the h-index and its variants. Our results show these indices correlate with the h-index and better identify top researchers. Some indices showed weak correlation, indicating ranking differences. We also analyzed awardees presence in ranked lists and top rankings in each index. The results show that the h-index, g-index, i10, E-index, citation count, and publication all performed well for approximately 42% of the awardees in the top 50 and 100 ranked lists. No index placed 100% of the awardees at the top of the rankings. Furthermore, our analysis indicates that the majority of American Society for Civil Engineers (ASCE) and Institute of Civil Engineers (ICE) awardees are at the top of ranking lists based on the h-index, rv-index, g-index, hg-index, and i10-index. This suggests a potential relationship between the h-index, rv-index, g-index, hg-index, and i10-index, and these awarding societies.
