New Scopus "Author Identifier" wows users

Amsterdam – June 12, 2006 – Scopus®, the world’s largest abstract and citation database of research information and quality Web sources, today announces that its new Author Identifier has received an enthusiastic reception from customers. Released on May 13th, the Scopus Author Identifier automatically distinguishes between authors with the same name and matches variations of author names. Using advanced algorithms Scopus is the first to “disambiguate” author names over such a comprehensive body of data. 

“In this first release we have achieved an extraordinary level of precision with over 99% certainty that records are matched to the correct author. We have already grouped over 95% of our records to authors which is quite an achievement over a base of 20 million author profiles - we are now focussed on fine tuning the recall. Now the system is live, the more data we add the better the recall will be” says Jaco Zijlstra, Scopus Director, “reactions from our users and customers have been extremely positive so far.”

Despite recent improvements, most abstracting databases still burden the searcher with identifying and selecting name variations. Although some databases cluster works by the specific format of author name, in general they don’t provide redirects to name variants1.

Instead of wasting time working through long lists of author names to check each one, with Scopus Author Identifier researchers can work with the confidence that they are getting the most comprehensive and accurate information as quickly as possible in a simple overview.

"This is a truly impressive achievement. We have been waiting for something like this for a long time. It is great to see that Scopus is the first to do this on such a large scale. It is so easy to use and solves a problem that many novices didn't even know they had and experienced users have long expressed a frustration with. It also builds on an existing strength of Scopus; supporting the collaboration between authors." Amy Knapp, Assistant University Librarian for Public Services and Departmental Libraries, University of Pittsburgh, USA.

How it works
The Scopus Author Identifier not only analyzes all the variants of the author’ name but utilizes additional data elements associated with the article such as affiliation, publication history, source title, subject area and co-authors. The highly sophisticated algorithms behind the Author Identifier are able to match author names with 99% accuracy and assign a unique identifier number to all authors who have published articles covered by Scopus. This has been achieved for 95% of records. Records with insufficient data to match with 99% confidence are not grouped until new data confirming the match is added to Scopus. As Scopus is continually updated records are matched constantly. Additionally, a feedback link on the Author Details page allows authors to check their details and tell Scopus if information needs to be adjusted.

“Immediacy and accuracy of the data makes the difference between a reliable database and ‘one more product’…. these changes you are making to Scopus makes it a more powerful tool” Daniel C. Baumgart,MD, PhD, Virchow Hospital, Germany.

Author Details page
Scopus has assigned an Author Details page to each author giving users an overview of data associated with that author. Not only are an individual authors’ papers grouped together for convenient viewing but the system also allows the researcher to make connections between people by viewing their co-authors and their co-authors’ articles. The user can also generate an instant overview of an author’s citations from the Author Page using the Scopus Citation Tracker. The Author Identifier also supports the exclusion of self citations at the simple click of a button on the Citation Tracker.

The new Scopus Author Identifier feature will be profiled from June 11th at the forthcoming Special Libraries Association Meeting in Baltimore, USA.
