Measuring your research impact

Citation analysis and Impact Factor

What is h-index?

Based on the research proposed by Hirsch (2005), “the index h, defined as the number of papers citation number ≥h, as a useful index to characterize the scientific output of a researcher”. Hirsch (2005), suggested a calculation wherein “a scientist has index h if h of his or her Np papers have at least h citations each and the other (Np – h) papers have ≤h citations each”. (DOI: https://doi.org/10.1073/pnas.0507655102).

In Scopus, h-index is not a static value rather it is calculated live on a set of results. (https://blog.scopus.com/posts/the-scopus-h-index-what-s-it-all-about-part-i)

Advantages of the h-Index:

  • Allows for direct comparisons within disciplines
  • Measures quantity and impact by a single value.

Disadvantages of the h-Index:

  • Does not give an accurate measure for early-career researchers
  • Calculated by using only articles that are indexed in Web of Science.  If a researcher publishes an article in a journal that is not indexed by Web of Science, the article, as well as any citations to it, will not be included in the H-Index calculation.

How to get h-index using Scopus

On this page, click the “Author Search” tab and create a search by typing the last name, first name (or first initials). Note: No special punctuation is required and multiple initials must be separated by a space.

The database will generate all the results at the bottom page. If there is more than one result for a given search, the database will list down all the related names to help you identify the author you want. Click the Author’s name to view the Author’s Profile/Details.

Within the Author’s Profile, you will find “View h-Graph” button to generate the h-index diagram. SCOPUS’s document and citation trends coverage start from 1997 to present.

The h-graph profile page will allow you to adjust different variables (ex. the range of dates of the documents published by the author) and it will automatically recalculate the h-index. The Analyze Author Output will show you the h-index of the author, documents submitted, number of citations, and even the co-authors.

The actual data shows the graphical presentation of Documents (by source, type, year, & subject), citations, and co-authors.
