What are h-index and i10-index

H-index

Introduction

• The h-index is short for the Hirsch index - Jorge E. Hirsch (2005).
• It\’s a metric at the author level that tries to measure both the productivity and citation impact of a scientist\’s or scholar\’s publications.

Calculating and Metric

• The h-index is simply a count of the largest number of papers (h) from a journal or author that have at least (h) number of citations.
• It arranges a researcher\’s published articles from highest to lowest citation count.
• It marks the point where citations equal or exceed the paper\’s rank
•  Although the h-index varies per discipline, it allows  comparison within comparable fields.

Increasing Your h-index

•  To increase the h-index, one must publish papers of high quality.
• The researcher should ensure that he/she has not published any article in predatory/fake journals.
• Researchers should make sure they have not published any articles in predatory or fake journals.
• However, publishing more review articles may result in more citations, ultimately increasing a profile\’s h-index.

Evaluating Academic Careers

• The h-index is used for assessing academic careers, particularly hiring and promotion decisions, and to compare scholars in the same field.
• Academic institutions and funding bodies use it to assess scholars for promotions, tenure, and grants.

Example for Calculation

•  For example, an h-index of 17 means the scientist has published at least 17 papers, each cited at least 17 times.
• The scientist\’s h-index remains 17 if their 18th most cited paper has only 10 citations.
  
• However, if the 18th most cited paper was cited 18 or more times, the h-index would increase to 18.

i10-index

Introduction to the i10-index

•  Google Scholar introduced the i10-index in 2011

Simple and Straightforward Indexing

• It\’s a basic index. Just count how many papers in a journal have 10 citations or more.
• The 10-citation benchmark is easy to grasp and sets a clear standard for what qualifies as a well-cited paper.

Complementing Other Metrics

• It works well with other measures like the h-index, giving more details about a researcher\’s productivity and influence.
• The i10 index also boosts the value of any student\’s profile.

Calculation and Accessibility

• The main advantage of the i10 index is that it can be calculated very easily.
• Google Scholar provides easy and free access to these metrics.

Indication of Quality Work

• A higher i10-index means consistently producing great work, which is crucial for success.
• Connecting with Google Scholar makes it easier to access and use for academic and research assessments.

Example of i10-index Calculation

• An i-10 index of 25 indicates that for every 25 articles published, the researcher has received at least 10 citations.
• This index varies among researchers, mainly based on their research subject and sub-sections.
