Other Author-level Metrices

Several other author level metrics are talked about.
i10: One such metric is i10, which gives the number of publications with citations equal or greater
than 10. It is a good index to check that an author has produced good number of publications with
reasonable quality and is noticed by his or her peer group. Depending upon different disciplines and
sub-disciplines one can make it ‘i-n’ where ‘n’ can be some number.

hc-index: If someone published a few highly-cited papers decades ago but presently is inactive, then
the h-index may be higher than an established researcher who continues to steadily publish, or a
promising new researcher who is just beginning to gain recognition. The hc-index (contemporary
h-index) weighs-in newer articles more heavily than older articles, to take into account the loss of their
research value over time. This allows a somewhat clearer picture of more recent levels of productivity
and impact.

m-index: This takes into account the lengths of careers of researchers while comparing citations, as
one who has been publishing for decades will certainly have higher h-index compared with a relatively
younger researcher.

Altmetrics ( Alt-metrics, Article-level Metrics, Alternative Metrics )

In the twenty-first century driven by the Internet, researchers are very keen to maintain their online
profiles through social networking, transnational forums and peer-to-peer collaborations. Citation-
based metrics have long been the accepted measure of scholarly productivity and quality, however,
increasingly authors and scholars are using basket of tools, usually referred to as Altmetrics. These
new generation tools essentially capture a holistic picture of how one’s research influences the creation
and dissemination of knowledge as well as how it is perceived by society at large.
Altmetrics assess broad spectrum online societal activity around any scholarly publications. These
new tools can be used by individual researchers, departments, institutions, publications, and more.
In addition to citations, these newer metrics include impact measures such as media coverage and
social media, Wikipedia and other quasi-scholarly platforms, news sources, and policy documents.
Specifically, it can include tweets, comments, shares or links, readers, subscribers, watchers or
followers, downloads, clicks or views, saves, bookmarks. and favourites. It can also include mentions
in mainstream media, in public policy documents, reviews, comments, ratings, or recommendations,
adaptations, or derivative works. There are several such metrics with the ever-expanding list.

Altmetric Attention Score (Altmetric.com)

The Altmetric Attention Score is presented within a colourful donut. Each colour indicates a different
source of online attention, ranging from traditional media outlets to social media, blogs, academic
forums, patents, policy documents, multimedia platforms, and so on. A strong Altmetric Score will
feature both a high number in the centre, and a wide range of colours in the donut.

Plum Analytics (plumanalytics.com)

Captures metrics for all types of scholarship and categorizes according to usage, captures, mentions,
social media, and citations. Specific products for institutions, institutional repositories, research
departments/groups, research funders.
