Siderean Software unveiled Seamark Navigator 4.0. Featuring new application integration, security and scalability enhancements, Seamark Navigator 4.0 enables business users to navigate and manage all types of structured and unstructured information across the enterprise. Key to Seamark Navigator 4.0 is the ability to enhance exploration and discovery from applications such as Google Enterprise Search and Oracle Secure Enterprise Search to help knowledge workers understand the scope and relationship of information available to them. With Seamark Navigator 4.0, users now have the ability to aggregate information from multiple sources regardless of format, navigate it quickly to illuminate previously unseen relationships so they can view what they don’t know, and humanize the information to access it with the least amount of clicks. Seamark Navigator 4.0 offers several new capabilities: External Search Integration with Google’s Search Appliance and Oracle’s Secure Enterprise Search; Role-Based Security to provide security at the facet level by filtering results based on the source of the information and the role assigned to the user; User Tagging to enable communities of interest to tag content for easy reference and enhance the navigational experience for all other users; Information Management Policies; Facet-Based Relevancy to enable the user to “boost” a facet allowing keywords found in that facet to have a higher priority than the same keywords found in another facet; Usage Analytics; On the Fly and Dynamic Facet Creation; and sixty-four bit scalability. Seamark Navigator 4.0 is immediately available.
