SEATTLE, WA, Dec. 6, 2005 -- Insightful Corporation (NASDAQ:IFUL), a leading provider of software solutions for analysis of numeric and text data, announced today the immediate release of Insightful Miner(TM) 7, a new update to the award winning data analysis workbench. This latest version leverages the Insightful Miner visual programming environment to provide faster and easier statistical analysis of very large databases and creation of predictive models. In addition, Insightful Miner 7 is designed to be fully compatible with S-PLUS(R) 7, a de facto industry standard software platform for statistical data analysis and predictive analytics.

Insightful Miner 7 provides statisticians, analysts and data miners, with comprehensive tools for data preparation, data cleaning, data modeling and prediction. A visual programming interface simplifies the creation and deployment of analytic solutions as well as their maintenance. Insightful Miner 7 is designed to integrate easily with other applications.

For users of Insightful's S-PLUS data analysis software, Insightful Miner 7 can be quickly adapted, allowing business users to create their own analyses and graphics without having to learn the S(TM) language. With Insightful Miner 7 Server, organizations can quickly deploy data analysis applications throughout the enterprise.

"With the explosion of information that is being collected by enterprises across all sectors, we are seeing a growing need by both technical and business users alike to be able to quickly and reliably extract actionable information from these data," said Kurt Schlegel, research director at Gartner. "Enterprises today are recognizing the need to deliver the power of statistical analysis across their organizations."

"One of the major challenges we faced in our work with NASA to support safety, security and reliability for Space Shuttle, Space Station and Space Ship programs was how to find relevant data in massive databases," said Dr. Travis Moebes, senior scientist and project manager for Science Applications International Corporation (SAIC).

"By deploying Insightful Miner along with our in-house text mining applications we were able to dramatically reduce the amount of time it takes to analyze NASA Corrective Action Reports from several weeks of engineer labor to just a few hours of analyst labor."

BENEFITS OF INSIGHTFUL MINER

-- Increased productivity through visual workforce interface. The visual workflow interface is designed to be easy to use, allow for greater productivity, be self-documenting and create an automatic audit trail of the entire process. In addition, the visual workflow interface helps team members collaborate, promotes analytic transparency and has change tracking functionality.

-- Open and extensible, ready to adapt to changing needs. Insightful Miner is integrated with Insightful's award winning S-PLUS data analysis software environment. With the drag and drop flexibility of Insightful Miner and the prototyping flexibility of S-PLUS, users are better able to build the statistical applications needed to fit into existing business processes or solutions, how and where they are needed. In addition, statisticians and business users can now incorporate new methods and models using the S programming language. For example, S-PLUS's sophisticated statistical techniques can be used to create predictive models and the predictive models can then be deployed to large databases with Insightful Miner.

-- Deliver custom charts and analytics to business analysts. Insightful Miner is designed to improve communication and collaboration between technical and business teams by delivering custom charts and analytics. Statisticians now have the ability to more effectively contribute to decision-making and efficiency throughout the organization by easily sharing their valuable work with business analysts. Publication quality graphics can be produced simply and can be fully customized. Statisticians can display results for business analysts through the use of charts and graphs that can then be leveraged across the broader business user audience.

-- Pipeline architecture for truly scalable data analysis. Insightful Miner's pipeline architecture is designed to allow for the analysis of very large data sets without being limited by the amount of physical RAM available. The only limitation is time and disk space. Insightful Miner's built-in components scale to data sets ranging in size from megabytes to multigigabytes.

-- Integrates statistics, where and how needed. Insightful Miner is designed to integrate easily with other applications using its industry standard batch-mode interface on Solaris(R) and Windows(R). Users can create run-time analytic applications with Insightful Miner's C-code generation tool to deploy predictive models in real-time applications.

KEY NEW FEATURES OF INSIGHTFUL MINER 7

-- Includes S(TM) language engine from S-PLUS 7.0 Enterprise enabling users to extend Insightful Miner with new, scalable tools, charts and analyses.

-- New and improved data processing nodes, including multi-stream merges and appends, a new duplicate detection tool and improved string and date handling within the data processing language.

-- Over 20 new and improved scalable charting nodes designed to enable the visualization of very large data sets without the need for sampling.

-- Enhanced file import and export, including support for 64-bit SAS(R) software files and export to the SVG graphics format.

-- Performance improvements for sort and merge operations.

"Insightful Miner 7 was developed to help customers more easily spread the benefits of statistical analysis and research based decision making throughout their organizations," said Jeff Coombs, president and chief executive officer of Insightful. "This latest version is especially designed to allow statisticians and business users alike to quickly and easily explore large databases and create predictive models that improve business performance, increase productivity and reduce costs."
