WebLib Develops Application for Elsevier's SciVerse Applications

HealthMash Application Delivers Relevant Biomedical Concepts Related to Searches

AMSTERDAM, December 13, 2010 - Elsevier (www.elsevier.com), a world-leading publisher of
scientific, technical and medical information products and services, today
announced that as a result of a partnership with WebLib (weblib.com/),
a new application, HealthMash, is now available on SciVerse Applications beta
(www.applications.sciverse.com/).

WebLib developed the HealthMash application to provide insights to
scientific researchers with relevant biomedical concepts related to their
searches including disorders, tests and diagnoses, treatments and drugs. The
application uses a variety of semantic technologies and natural language
processing tools. HealthMash is powered by WebLib's proprietary Health
Knowledge Base, which is automatically generated from trusted health content
sites, special semantic sources such as the National Library of Medicine's
Medical Subject Headings Thesaurus, and the Unified Medical Language System
as well as information from the Web.

"WebLib's HealthMash application is powered by our consumer Health
Knowledge Base and our goal is to create a much larger Science Knowledge Base
to support semantic search applications on SciVerse and the emerging Semantic
Web," said Dr. Tamas Doszkocs, President and Chief Scientist, WebLib LLC.

The addition of HealthMash to the SciVerse Applications beta marketplace,
which currently includes 17 applications, illustrates the capabilities of the
new platform to advance the scientific search and discovery process. All
applications in the market place are designed to improve researcher workflow
and enhance the content within SciVerse.

"Our collaboration with WebLib, as well as other commercial and academic
partners, aims to enhance researchers' productivity," explained Rafael Sidi,
vice president of product management for Elsevier's Application Marketplace
and Developer Network. "We look forward to expanding our collaboration with
academic and commercial developers as well as providing additional innovative
applications that will improve researchers' search and discovery experience."
