The pursuit of happiness

on Fri, 03/20/2015 - 12:59

What does it mean to be happy? On an individual level, a career, a family, a social life, a home, a hobby, education and health could define happiness. Happiness has long been a holistic approach based on the fundamental idea that material and tangible gain must be balanced with emotional and social well-being.

The International Day of Happiness is March 20th and was declared a holiday by the United Nations to celebrate the happiness of individual nations across the globe. Countries looked at Gross National Product and realized that simply looking at the bottom line in terms of income doesn’t define the well-being of the country as a whole. Social and environmental considerations are equally as important.

The Sustainable Development Solutions Network releases an annual report that measures the happiness of 150 nations around the world.


Total eclipse of the sun (and who’s studying it)

on Thu, 03/19/2015 - 13:17

Day will turn into darkness on Friday, March 20 during a total solar eclipse - a phenomenon which occurs when the moon's apparent diameter is larger than the sun's, blocking all direct sunlight. But no need to alarm; totality will only have a maximum duration of 2 minutes 47 seconds off the coast of the Faroe Islands.

Looking at Scopus content related to solar eclipse from 1836 to the present, it is interesting to see how scientific output is spread across an array of different disciplines, stretching from astronomy and planetary sciences to engineering, medicine, and social sciences.

Carrying significant impact upon existing energy supplies, solar eclipses are being studied by researchers across the globe. Focusing on the scientific landscape for research area “solar eclipse” in SciVal, we had a look at the top countries and institutions over the last 5 years (2010-2015). In terms of scholarly output (as well as total number of views), the

Happy Saint Patrick's Day! (+3 facts about the Irish research landscape)

on Tue, 03/17/2015 - 12:53

Celebrating Irish culture and heritage, Saint Patrick's Day is observed every year on March 17 in commemoration of Saint Patrick (c. AD 385–461), patron saint of Ireland.

Before donning our green shirts and running to the nearest Irish pub for a pint of Guinness, we wanted to have a closer look at how Ireland is performing  in terms of scientific research and output.

Here is Ireland's overview in SciVal for the period 2012-1014:

As shown in the above chart, the color of the three-leaved shamrock also has its share in contemporary Irish research: 14.2% of all publications lie within the green subject areas (biochemistry, genetics, molecular biology, agricultural and biological sciences).

Digging deeper into the Scopus-based data in SciVal, here are 3 things we found out about the Irish research landscape:

1. The top 3 institutions in terms of number of publications and total citations are: University College Dublin, Trinity College Dublin,

Celebrating the ultimate pi moment

on Fri, 03/13/2015 - 09:49

Pi Day is observed annually on March 14, commemorating the famous mathematical constant π (pi) that represents the ratio of the circumference of a circle to its diameter.

On the occasion of Pi Day we dug through our Scopus math content: from a total of 2.3M+ results for subject area ''mathematics'', 71.4% of the content comes from journal articles, while 22.7% is derived from conference papers (compared to 82.3% and 15.1% respectively from one year ago).

We are pleased to announce that the inaugural and recently-released "2015 Best Chinese University Ranking" report, based on evaluation by the ShanghaiRanking Consultancy (SRC), is using Scopus data and metrics from SciVal analytics. A truly exciting start to the Year of the Sheep (as 2015 is referred to by the Chinese zodiac)!

The report provides a detailed look at key research performance indicators of more than 1,000 higher education institutions across mainland China. SRC's ranking of Chinese universities offers objective benchmarking of research performance of higher education institutions, allowing research management offices and higher education agencies to make strategic decisions around policy development and investments towards building the research capabilities of these universities.

Further to SRC, Scopus data and SciVal analytics also support Times Higher Education's World University ranking, US News &

Scopus Conference Expansion Program exceeds targets

on Thu, 02/19/2015 - 10:01

We are happy to announce that the Scopus Conference Expansion Program (CEP) is now complete, exceeding its original goal with over 1,000 conference titles, 6,000 conference events and 400,000 conference papers newly covered in both Scopus and Ei Compendex. The Conference Expansion Program, which ran from 2011-2014, consistently focused on disciplines where the communication of findings at international meetings is especially important, primarily Computer Science and Engineering, boosting the citation levels of researchers in these fields.

Conference coverage currently represents around 15% of the content loaded in Scopus, where it provides an important additional component to the scientific literature. Besides filling gaps in the coverage of conference-oriented disciplines, the influx of CEP coverage helps users to monitor the emergence of new concepts in other subject areas, tracking their passage into formal research papers.

Covering the key period of 2005 to the present, the CEP

2014 – Scopus’ Year in Review

on Mon, 01/05/2015 - 10:07

2014 was a banner year for Scopus featuring great releases, further content expansion for all content types and continuous product improvements based on your feedback. Let’s take a closer look at last year's high points:

  • First, 2014 marked the 10th anniversary of Scopus. Since its launch in 2004, Scopus has grown to become the largest abstract and citation database of peer-reviewed literature, containing 55 million records and more than 21,000 journals from all major fields.

  • In combination with our 10 year anniversary, we initiated a site improvement program resulting in the launch of a more streamlined interface. This was followed by a redesign of the Author Profile Page as well as the introduction of a Simplified Chinese user interface and help files (to learn more about this release, check out the full release notes).

Scopus continues to add pre-1996 citations

on Mon, 12/08/2014 - 09:30

In March, we launched the Cited Reference Expansion Program to include cited references in the Scopus database going back to 1970 for pre-1996 content. Our goal is to expand the ability for users to perform long-term, extensive bibliometric and historic trend analyses – and enhance h-indices for those researchers who published pre-1996.

As of November 1st we started re-indexing content and pre-1996 archives with cited references are now loaded on a daily basis. There are currently 500,000+ pre-1996 items with cited references in Scopus. This is having a positive impact on the h-index of senior researchers, making author profiles and h-index counts for these researchers more accurate and complete.

To illustrate this content improvement, we have been tracking the number of total citations and measuring the difference of the h-index for a sample set of authors from various subject areas between June and December.

Meet the Scopus celebrities

on Thu, 11/27/2014 - 12:10

With a total of 55 million records, Scopus delivers a comprehensive overview of research in the fields of science, technology, medicine, social sciences, and the arts and humanities. Inevitably, some of the authors indexed in Scopus are bound to be more popular or have more impact than others.

Certain authors, however, are true celebrities of worldwide fame (achieved, incidentally, not merely on scientific merits). We'd like to introduce you to some of them.

Brian May: Rocking the astrophysics

Apart from being the lead guitarist of celebrated rock group Queen, English musician Brian May also studied physics and mathematics at Imperial College in London. He started his PhD on the motion of interplanetary dust particles in 1970 which, mainly due to musical commitments, he was finally able to complete in September 2007. Asteroid 52665 Brianmay is named in his honour.

Research Trends: Special Issue on the 10 years of Scopus

on Fri, 11/21/2014 - 09:49

Since its launch in the fall of 2004, Scopus has established itself as the largest abstract and citation database of peer-reviewed research literature. In honor of the 10th anniversary of Elsevier’s bibliographical database, Research Trends recently published a Special Issue that looks back on these 10 years and illustrates how Scopus can be used in bibliometric studies of trends in the global science system.

For one of the issue’s contributions, Dr. Gali Halevi and Dr. Henk F. Moed conducted a comprehensive search on all Scopus data (limiting the results to full research articles only), coming up with a list of the most frequently cited articles published between 2001 and 2011 in eight main research areas. According to their findings, these were the top cited articles per research area:
