Research Impact Metrics and Altmetrics: New Tools for Measuring Scientific Impact

In today’s world of science and research, measuring the impact and significance of scientific publications has become an integral part of academic life. Traditionally used metrics such as the Impact Factor for scientific journals do not always provide a complete picture of research impact. In response to this challenge, new tools and metrics, such as altmetrics, have emerged to allow for a more comprehensive and individualized approach to measuring scientific impact. In this article, we will take a closer look at research impact metrics and altmetrics, analyzing their significance, advantages, and limitations.

Research Impact Metrics

Impact Factor

Impact Factor (IF) is one of the most well-known and commonly used tools for measuring the impact of scientific journals. Developed in the 1960s by Eugene Garfield, IF is based on the number of citations of articles published in a specific journal during a defined period. IF is calculated as the ratio of the number of citations to the number of articles published in the journal during the two years preceding the target year. IF is widely used for assessing the prestige of scientific journals and is often utilized in academic recruitment and grant allocation processes.

However, IF has its limitations. Firstly, it focuses exclusively on scientific journals, omitting other forms of publications such as books, conferences, or online data. Secondly, IF is susceptible to manipulation, as authors and journal editors sometimes attempt to increase citation counts, for instance, by publishing self-cited articles. Additionally, IF does not consider the quality of the citations themselves, which can lead to an overestimation of the impact of certain journals.


The H-index, proposed by Jorge Hirsch in 2005, is another popular metric used to evaluate the impact of researchers. It is based on the number of publications and the number of citations those publications have received. A researcher has an H-index of h if they have h publications, each of which has been cited at least h times.

The H-index is used in academic recruitment, career advancement, and grant allocation processes. It provides a fairly stable metric that takes into account both the quantity of publications and their impact on the scientific community. However, the H-index also has limitations, especially for young researchers who have not yet built a substantial body of work.


With the development of technology and the internet, new methods of measuring scientific impact have emerged that attempt to go beyond traditional metrics. Altmetrics, short for “alternative metrics,” is one of these innovative approaches.

What Is Altmetrics?

Altmetrics is a collection of tools and techniques used to measure the impact of scientific publications on the internet and social media. Unlike traditional metrics that focus on citations in scientific journals, altmetrics consider a wide range of indicators, such as download counts, shares, comments, likes, tweets, and other online interactions related to scientific publications.

Altmetrics allow researchers to track how their work is disseminated online and how it impacts different target groups. This provides a more comprehensive picture of research impact than traditional metrics.

Advantages of Altmetrics

Speed of Measurement

One of the main advantages of altmetrics is its speed. Traditional metrics like Impact Factor and H-index require time to collect data and calculate results. Altmetrics, on the other hand, allow researchers to monitor online interactions almost in real-time. Researchers can learn about the interest in their work shortly after publication.

Inclusion of Diverse Sources

Altmetrics consider diverse sources of information, including social media, websites, blogs, discussion forums, and more. This enables a better understanding of how scientific publications influence various social groups and their practical consequences.


Altmetrics are versatile and can be applied to various types of scientific publications, including articles, preprints, research data, conference presentations, and more. They also cover a wide range of scientific fields, allowing for comparisons of research impact across disciplines.

Limitations of Altmetrics

Complex Analysis

Analyzing altmetric data can be complex and time-consuming. There are many different tools and platforms for monitoring online interactions, each providing different types of data. Understanding and interpreting this data requires some knowledge and experience.

Vulnerability to Manipulation

Like traditional metrics, altmetrics are susceptible to manipulation. Authors may try to increase the number of likes or tweets related to their publications, which can influence altmetric results.

Lack of Uniform Standards

Currently, there are no uniform standards for altmetrics. There are many different altmetric tools and metrics, making it challenging to compare results between different studies.


Research impact metrics and altmetrics are essential tools for measuring scientific impact, but they differ in scope and approach. Traditional metrics like Impact Factor and H-index primarily focus on journal publications, while altmetrics take into account a broader range of online indicators. Altmetrics can be particularly valuable for researchers who want to track how their work is disseminated on the internet and how it affects various target groups. However, each of these metrics has its limitations and should not be used in isolation. It is worthwhile to use a variety of tools for measuring research impact to obtain a more comprehensive and dynamic understanding. As technology and research on scientific metrics continue to evolve, we can expect further innovations in this field that will help us assess the impact of science on the world more accurately.
