Veterinary - Scholarly Communications: Measuring impact

What is research impact? Why is it important?

Research impact seeks to quantify the academic, economic, and societal impact of research. Measuring and describing your research impact demonstrates the value of your work as you seek grant funding and apply for promotion or tenure. The information below explains various author impact factor measures and can help you assess the impact of your research.  

Types of author impact factors

H-Index (Hirsh Index)

H-Index "is defined as the highest number of publications of a scientist that received h or more citations each while the other publications have not more than h citations each."1

Calculate H-Index with Web of Science, Google Scholar, or Publish or Perish. Please note h-index calculations may vary between databases.

G-Index

G-Index "is given by the largest number g of papers which have received at least g citations on average."2

i10 Index

i10 index is a Google Scholar metric that measures a researcher's number of publications with at least 10 citations.

Citation impact

Web of Science

From the Web of Science site, you can create a ResearcherID and Publons Researcher profile; once you have claimed your publications, your Publons Researcher profile automatically calculates your h-index, as well as other metrics.

Within Web of Science, you can also complete an author search to create a citation report that will calculate the author's h-index.

Google Scholar Profile

Once you have created a Scholar Profile and claimed your publications within Google Scholar, your profile will automatically calculate both your h-index and i10 index.

Publish or Perish

This free, downloadable software uses citation data from Google Scholar and Microsoft Academic Search to calculate a variety of metrics, including both h-index and g-index.
