PHILADELPHIA and LONDON, February 21 /PRNewswire/ --

- Thomson Collexis Dashboard to Provide Scientists and Researchers with
Deep Analysis, Trending, and Visualization of Published Information

Thomson Scientific, part of The Thomson Corporation (NYSE: TOC; TSX: TOC)
and leading provider of information solutions to the worldwide research and
business communities, and Collexis Holdings Inc. (OTC Bulletin Board: CLXS),
a developer of high definition search and knowledge discovery software, today
announced plans to join together Collexis' Knowledge Dashboard with Thomson
Scientific's Web of Science to create a custom data mining solution for the
research community.

Called the Thomson Collexis Dashboard, it will provide enhanced knowledge
discovery for the academic and government R&D communities. By merging Thomson
Scientific's Web of Science data with the Collexis Knowledge Dashboard, users
will have the ability to identify and search for documents, experts and
trends, and make new discoveries more quickly, accurately and deeply than via
conventional search engines.

"By marrying the data and functionality of our technology and domain
expertise in the life sciences with Thomson Scientific's extensive research
journal database, we are enabling users to take their research to the next
level," said Bill Kirkland, CEO of Collexis Holdings, Inc. "The Thomson
Collexis Dashboard will offer expanded capabilities for researchers to search
and analyze journals and cited research back to 1985, as well as use this
unique resource to discover emerging research paths, new hypotheses and
experts."

The Thomson Collexis Dashboard is a custom software and information
solution that enables scientists to analyze large numbers of publications
concerning a defined topic swiftly and efficiently, and filter the essential
information. Additionally, it allows researchers to explore existing
knowledge concepts and provides proactive suggestions about the direction of
research across a topic or by category. It also includes multiple thesauri
that allow different points of view on the same data and subject navigation.
A time-saving solution for scientists, the Thomson Collexis Dashboard
includes summarized information which is not to be found in any system
currently available, and provides identification of experts across categories
on multiple subsets of the literature instantly -- including their relevant
social network.

The Web of Science provides seamless access to current and retrospective
multidisciplinary information from close to 9,500 of the most prestigious,
high impact research journals in the world. Web of Science also provides a
unique search method through cited reference searching. With it, users can
navigate forward, backward, and through the literature, searching all
disciplines and time spans to uncover all the information relevant to their
research. Users can also navigate to electronic full-text journal articles.

"Thomson Scientific is dedicated to providing our customers with powerful
ways to mine the published literature," said Dave Kochalko, vice president,
business strategy at Thomson Scientific. "Turning the Collexis engine on Web
of Science will expose new insights and give users the tools to make ground
breaking discoveries on specific topics in the life sciences, such as
Alzheimer's or Diabetes, or any research discipline."

designed dashboards for Web of Science, please e-mail: info@collexis.com
