Impact factors and citation metrics

The adoption of the REF means that universities are under enormous pressure to produce publications, particularly peer-reviewed journal articles. A controversial aspect of the REF is the proposal to use metrics based on a ‘citation count’ as one means of measuring research performance.

A citation count is a measure of the number of times that books or articles published or co-published by the researcher have been cited in other academic papers. In general terms, the more publications a researcher or team has, the more likely they are to be cited in publications by their peers. The Institute for Scientific Information (ISI), now part of Thomson Reuters, publishes an online list of ‘Highly Cited Researchers’ - those whose publications were most often cited over the last decade. Inclusion in this list is taken as a measure of the esteem of these academics.

Citation metrics are the basis of another commonly used measure of prestige: the ‘Impact Factor’ of a journal. The impact factor is a number derived from the average number of citations gained by articles published in the journal. The ISI publishes impact factor data annually. Because articles in journals with a high impact factor tend to be cited more often than articles in journals with a lower impact factor, publication in a ‘high impact factor’ journal is often seen as an indication of the quality of the article.

Some academics maintain that citation metrics do not accurately reflect the importance of published research or the success of the authors or groups who publish the papers. In particular, as early career researchers tend to have relatively few publications to their name, their citation counts are lower than those of more established names. Researchers who develop widely used methodologies achieve large numbers of citations even though they may not be publishing original research. And those who write for the popular presses inevitably gain more citations than those who confine themselves to more specialist academic journals, regardless of the quality or originality of what they are publishing.

In many disciplines, it used to be common practice for research teams to publish large numbers of short articles (often described as ‘letters’) in specialist journals designed for rapid publication of new discoveries. Researchers were often able to use these journals to make an impact early on in their careers. The picture has changed, however, as impact factors have assumed a greater importance. Many of the ‘rapid publication’ journals are in specialist fields and as such their impact factors are relatively low. Some institutions now actively discourage publication in these journals, requiring researchers to ‘save up’ their results until they can be published as a major article in a high impact factor publication instead.

Whether or not these changes are beneficial to the academic community is open to debate. However, the reality appears to be that citation metrics are here to stay. Researchers need to bear these issues in mind when considering when and where to publish.
