New citation indicators needed to measure research performance

12.02.2013
How do you compare the impact of a researcher in chemistry or physics with a molecular biologist who may be working on similar projects?
In an article published today in EMBO reports two experts support the use of citation indicators that are based on percentiles, a statistical parameter that allows for comparisons with a carefully defined group of reference data. Journal impact factors and h-index alone do not make the grade.

“We argue that new citation impact indicators are needed and that these indicators should allow the comparison of the observed impact for a given publication set with a reference set of similar publications,” said Lutz Bornmann, a sociologist of science at the Division for Science and Innovation Studies at the Max Planck Society in Munich, Germany. “This is a better way to make meaningful assessments of scientific work.” He added: “Indicators must also take into account that the distribution of citations across papers is often skewed. The use of percentiles described in our paper provides a solution.”

A scientific paper and its citation in other papers reveal how science makes progress and can help to establish the credit for new discoveries. Citation indicators are used extensively to evaluate the impact of the research of individual scientists, institutes and university departments, and sometimes even countries. The outcomes of such analyses can have a profound influence on the careers of scientists or, for example, the future funding of research institutes.

The authors of the study emphasize that journal impact factors and h-index, two frequently used parameters to evaluate the quality and quantity of science, do not readily allow for comparisons between the work of different scientists or publications in journals from unrelated research fields. The problem is similar to comparing the performance of individuals who score goals in sports as different as football and handball. The number of goals in football is often around 2 but in handball can reach 20 or more. Is someone who scores an average of five goals in handball a better athlete than a football player who scores one goal a game?

“Experts of bibliometrics avoid using journal impact factors and the h-index because these indicators do not provide normalized values. For many years, they have been using reference sets to normalize the number of citations which is indispensable for fair assessment,” commented Werner Marx, co-author of the paper and head of the Information Retrieval Services at the Max Planck Institute for Solid State Research in Stuttgart, Germany. “The use of this type of advanced analysis is growing. However, we have an opportunity to do more and this could have a big impact on the way we answer important questions such as how good research really is.”

How good is research really? Measuring the citation impact of publications with percentiles increases correct assessments and fair comparisons

About EMBO
EMBO is an organization of more than 1500 leading researchers that promotes excellence in the life sciences. The major goals of the organization are to support talented researchers at all stages of their careers, stimulate the exchange of scientific information, and help build a European research environment where scientists can achieve their best work.

EMBO helps young scientists to advance their research, promote their international reputations and ensure their mobility. Courses, workshops, conferences and scientific journals disseminate the latest research and offer training in techniques to maintain high standards of excellence in research practice. EMBO helps to shape science and research policy by seeking input and feedback from our community and by following closely the trends in science in Europe.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
