Elsevier Introduces Chemistry Application That Helps Researchers Unravel Deep Layers of Information

New Interoperability Between ScienceDirect and Reaxys Improves Discoverability and Visualization of Chemical Structures

AMSTERDAM, July 20, 2010 - Elsevier, a world-leading publisher of scientific, medical and technical
products and services, today introduced a new feature on ScienceDirect that
improves the discoverability and usefulness of scientific chemistry content.
As such, this added functionality enhances the value of the content for both
authors and readers in chemistry.

Starting with two Elsevier chemistry journals, authors are invited to
submit structure (MOL) files of their key compounds alongside their articles.
Elsevier will use these structure files to add compound identifiers -
International Chemical Identifier (InChI) keys* - to the article, increasing
the discoverability of both the article and its key compounds on
ScienceDirect and through search engines. In addition, the structure files
are used to visually display all key compounds of the article in a single
scrollable list, with additional functionality such as links to Reaxys
(https://www.reaxys.com/reaxys/session.do), Elsevier's web-based chemistry
database, and Google.

"By employing the structure files as submitted by the author, this new
feature improves the value of our content above and beyond what can be done
automatically through, for instance, text mining. It ensures that the most
relevant compounds are identified, visualized, and made available for search
and download", said IJsbrand Jan Aalbersberg, Vice President for Content
Innovation at Elsevier. He added: "Making the MOL files of key compounds
available at ScienceDirect (www.sciencedirect.com/) and, at the same
time, using Reaxys to show the corresponding structures, ties into Elsevier's
strategy to enrich the content of ScienceDirect. The use of InChI keys
improves discoverability of compounds within the chemistry scientific
literature, facilitating and accelerating connectivity to other research
tools and content sources. It helps researchers unravel deep layers of
information, otherwise hidden in the full text, therewith increasing their
research productivity."

The new feature will greatly enhance the utility of ScienceDirect
articles and allow readers to easily go beyond the content of an article and
to view chemical compounds in a much broader scope. Creating sub-structure
searches in Reaxys(R) directly from within an article has never been easier;
a simple mouse-click can provide insights that would not have been discovered
before.

The linking of data and content has the potential to streamline the
research process, bringing to researchers more relevant information with
fewer clicks and through quicker searches. With this in mind, ScienceDirect
has built the capability to quickly plug in specialized applications as they
are developed, so that external data or relevant analysis tools can be
integrated directly in the online article as opportunities emerge. More of
such integrations are planned for the near future.
