Researcher evaluation measures do not add up

The h-index is a widely used measure, but it has significant limitations, including being skewed by specific fields and failing to account for impact beyond the scientific community. Researchers should consider alternative metrics like altmetrics to gain a more complete understanding of a researcher's influence.

Exact formula now available for measuring scientific success

A Polish team has developed an analytical method to predict the h-index, a key scientific measurement, using bibliometric data. The study provides an exact formula to calculate external citations and self-citations for each paper written by an author, opening doors for growth analysis in social networks and different scientific fields.

Study: Models to predict scientists' future impact often fail

Researchers at Aalto University found that current models for forecasting scientist's future contributions are unreliable and can grossly overestimate their predictability. The study analyzed 762 scientists from three disciplines and identified subtle flaws in current models, including false autocorrelation and varying predictive power...

New citation indicators needed to measure research performance

Researchers argue that traditional citation metrics like journal impact factors and h-index are insufficient for comparing the impact of different scientists or publications in unrelated fields. Percentile-based indicators can provide a more accurate assessment of scientific work.

Predicting if scientists will be stars

A new Northwestern University study developed a formula that accurately predicts a young scientist's success in the life sciences, considering factors like publications, h-index, and high-impact journal articles. The formula is more than twice as accurate as existing methods for predicting future success.

UCSD physicist proposes new way to rank scientists' output

A new method to rank scientific output has been proposed by a UCSD physicist, using the h-index to estimate a scientist's cumulative research contributions. The h-index is derived from citation counts and provides a single number that can be used to compare relative ranks within a discipline.
