Quantity does matter as citation impact increases with productivity

Many scholars are encouraged to focus on the quality not the quantity of their publications, the rationale being that becoming too focused on productivity risks reducing the quality of one’s work. But is this, in fact, the case? Peter van den Besselaar and Ulf Sandström have studied a large sample of researchers and found that, while results vary by field, […]

2017 in review: round-up of our top posts on metrics

Mendeley reader counts offer early evidence of the scholarly impact of academic articles Although the use of citation counts as indicators of scholarly impact has well-documented limitations, it does offer insight into what articles are read and valued. However, one major disadvantage of citation counts is that they are slow to accumulate. Mike Thelwall has examined reader counts from Mendeley and found them […]

Where are the rising stars of research working? Towards a momentum-based look at research excellence

Traditional university rankings and leaderboards are largely an indicator of past performance of academic staff, some of whom conducted the research for which they are most famous elsewhere. Paul X. McCarthy has analysed bibliometric data to see which research institutions are accelerating fastest in terms of output and impact. The same data also offers a glimpse into the future, helping […]

Does research evaluation in the sciences have a gender problem? What do altmetrics tell us?

Many measures used for research evaulation, such as citations or research output, are hindered by an implicit gender bias. Stacy Konkiel examines whether or not altmetrics, which track how research is discussed, shared, reviewed, and reused by other researchers and the public, might be better suited to help understand the influence of research in a more gender-balanced way. Findings suggest […]

The methodology used for the Times Higher Education World University Rankings’ citations metric can distort benchmarking

The Times Higher Education World University Rankings can influence an institution’s reputation and even its future revenues. However, Avtar Natt argues that the methodology used to calculate its citation metrics can have the effect of distorting benchmarking exercises. The fractional counting approach applied to only a select number of papers with high author numbers has led to a situation whereby […]

The new configuration of metrics, rules, and guidelines creates a disturbing ambiguity in academia

Much of academia has become increasingly influenced by metrics and a set of metrical practices. However, few have totally understood the massive wave of conflicting rules and guidelines that are necessary in order to stabilise these metrical practices. Peter Dahler-Larsen, using examples from his own experiences in Denmark, explains how these multiple, cross-cutting rules have created a disturbing ambiguity in […]

Me, myself, and I: self-citation rates are higher in individualist cultures than in collectivist cultures

Citing your own work when publishing a paper may be seen as a way of promoting yourself in academia, as how frequently a paper is cited is often viewed as a measure of its importance. Previous studies have shown that male authors are more likely than their female counterparts to cite themselves, arguably one of the reasons men continue to […]

Microsoft Academic is on the verge of becoming a bibliometric superpower

Last year, the new Microsoft Academic service was launched. Sven E. Hug and Martin P. Brändle look at how it compares with more established competitors such as Google Scholar, Scopus, and Web of Science. While there are reservations about the availability of instructions for novice users, Microsoft Academic has impressive semantic search functionality, broad coverage, structured and rich metadata, and […]

How do LSE blogs impact the academic sphere? Blogs as citable items in scholarly publications

In the third of a series of posts on the Impact of LSE Blogs project, Carlos Arrebola takes a closer look at the increasing frequency with which LSE blog posts are being cited in scholarly publications. The Impact Blog has been cited most often, perhaps reflecting its authors’ readiness to draw on non-traditional scholarly outputs. Unsurprisingly, a majority of citations come from […]
