The h-index, a measure of scientific impact, varies across databases for Brazilian researchers. Google Scholar better captures the bibliometric impact in fields with strong professional components and native language publications.
Area of Science:
- Public Health
- Immunology
- Medicine
Background:
- The h-index is a widely used metric for assessing the bibliometric impact of researchers' scientific output.
- Evaluating bibliometric impact requires careful consideration of the database used for analysis.
Purpose of the Study:
- To analyze the utility of the h-index for measuring the bibliometric impact of Brazilian researchers' scientific publications.
- To compare the h-index across different scientific disciplines and databases.
Main Methods:
- Compared the scientific production of Brazilian CNPq 1-A researchers in public health, immunology, and medicine.
- Estimated the mean h-index for each group.
- Utilized nonparametric Kruskal Wallis and Behrens-Fisher tests for statistical comparisons.
Main Results:
- The h-index was higher in Immunology compared to Public Health and Medicine when using Web of Science.
- This difference in h-index means diminished when using Scopus or Google Scholar databases.
- Google Scholar may offer a more comprehensive measure in certain fields.
Conclusions:
- The emergence of Google Scholar impacts discussions on bibliometric impact measurement.
- Fields with strong professional components and native language publications have distinct citation patterns.
- Google Scholar appears to better capture the bibliometric impact in these fields compared to traditional academic databases.
