Evaluation Based on Completeness of Vision and Ability to Execute

El Segundo, Calif., Sept. 12, 2007

Siderean Software, the leading provider of relational navigation solutions, today announced it has been positioned by Gartner, Inc. in the Visionaries quadrant in the ‘Enterprise Information Access Magic Quadrant’ⁱ Report by Whit Andrews dated September 5th, 2007.

“We think our position in Gartner’s Visionaries quadrant validates our mission of helping enterprise users master discovery with relational navigation,” said Michael Schmitt, CEO of Siderean Software. “With rich navigation, analytics, and relevancy capabilities that help users discover what they did not know to look for on their own, Siderean’s Seamark Navigator unlocks the power of information access by dramatically improving the way people retrieve, organize, and discover information. We believe being placed in the Visionaries quadrant demonstrates we deliver a truly unique and valuable product that meets the most demanding requirements set by our customers. Users across the high-tech, media and government continue to inspire us to push the innovation envelope and support us as we execute on our product roadmap.”

According to Gartner, this Magic Quadrant includes “vendors with capabilities that go beyond enterprise search to encompass a collection of technologies, including: search; content classification; categorization and clustering; fact and entity extraction; taxonomy creation and management; information presentation (for example visualization) to support analysis and understanding; and desktop (or personal knowledge) search to address user-controlled repositories to locate and invoke documents, data, e-mail and intelligence.”

With its patented relational navigation technology, Siderean’s Seamark Navigator 4.5 goes beyond search to provide users with categorization, taxonomy creation, and customized visual presentation features enhancing their information access experience. By combining these capabilities, Siderean also offers users the unique ability to dynamically identify relationships between sets of information and create the context to drive action, all while increasing their participation in the information flow. Customers already realizing substantial business benefits from Siderean’s relational navigation technology include Oracle Corporation, NASA Jet Propulsion Laboratory, Snap-On Incorporated, SpendMatters and the Librarian’s Internet Index.
