ScholarRank is determined by the calculation of HeinOnline ScholarCheck metrics, h5-index, and h-index. The Z-score for each of the five metrics is taken and then averaged; the final average is entered into the standard competition ranking to produce the overall ScholarRank for each author. The raw data and final ranking are regularly updated every month and can be found on the HeinOnline author’s profile page.
How We Calculate ScholarRank
irst, the raw data is gathered for each of the five metrics. These metrics are:
- Cited by Articles (0-5 Years)
This metric counts the number of times this author has been cited by other articles in HeinOnline within the past five years only. Citation style sources include the Bluebook, Prince’s Dictionary of Legal Abbreviations, and the Cardiff Index to Legal Abbreviations. - Cited by Articles (5+ Years)
This metric counts the number of times this author has been cited by other articles in HeinOnline beyond the past five years only. Citation style sources include the Bluebook, Prince’s Dictionary of Legal Abbreviations, and the Cardiff Index to Legal Abbreviations. - h5-index
The h5-index is an author-level metric that attempts to measure both the productivity and citation impact of an author’s publications over the most recent five complete calendar years. The index is based on the number of papers (h) published by the author in that period that have each been cited at least h times. This metric provides a more current snapshot of an author’s research influence than the traditional h-index. - h-index
The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of an author. The index is based on the set of the author’s most cited papers and the number of citations that they have received in other publications. - Accessed (Past 12 Months)
This metric is used to account for relevancy & recency and counts the cumulative number of times an author’s articles have been accessed by HeinOnline users within a rolling 12-month period. For an author’s article to count as accessed, the article must be clicked from either search results or by browsing to the article, or retrieved using the citation navigator.
This raw data is then displayed on the author’s profile. For example:
Next, the Z-score is calculated for each of the five metrics. The five Z-scores are averaged, and the final average is entered into the standard competition ranking. The author’s standing within this ranking produces the author’s final ScholarRank.
ScholarRank is calculated in the following manner:
Z-Score Calculation (to calculate the Z-scores of each metric): Zx = (x-µ)/σ
Average Z-Score (determined by averaging the five Z-scores): Zµ = (Z1 + Z2 + Z3 + Z4 + Z5)/5
Final ScholarRank (determined by ranking each author’s Average Z-scores): Zµ, ranked by standard competition
Though rare, it is possible for multiple authors to have the same ScholarRank.
*Standard deviations and averages fluctuate daily; as such, the final results are subject to change.
