The JSR-247 expert group, defining Java Data Mining (JDM) 2.0, submitted the Early Draft of the specification for public comment to the Java Community Process November 30, 2005. The early draft phase of the Java Community Process gives the Java community and public an opportunity to provide the expert group feedback as they continue to refine the standard for the public draft and then final release.

JDM 2.0 builds upon the specification released in August 2004 by addressing new mining functions for Time Series, Feature Extraction, multi-target models, and Anomaly Detection. It also expands support for efficient multi-record real-time scoring, introduces prediction for Association models, and provides a framework for defining and using transformations and transformation sequences, among other enhancements.

Those interested in reviewing the specification can download it at http://www.jcp.org/en/jsr/detail?id=247. The official review period began December 12, 2005 and extends through January 11, 2006. Comments on the specification can be submitted to jsr-247-comments@jcp.org.

Java Data Mining provides a framework for performing data mining operations, while facilitating the introduction of new or non-standard mining algorithms. By separating algorithm details from function level specification, JDM strives to make data mining accessible to mining experts and novices, while allowing vendors to differentiate themselves on features, performance, and automation.

The Java Data Mining 1.1 final specification is available at http://www.jcp.org/jsr/detail/73.jsp. Commercial implementations of the standard exist through Oracle (http://www.oracle.com/technology/products/bi/odm/index.html) and KXEN (http://www.kxen.com). Other vendors are in the process of developing compliant products. The expert group has seen notable interest from companies leveraging JDM for internal data mining interfaces.

To facilitate public exchange of ideas on JDM, the project “datamining” has been created on java.net at https://datamining.dev.java.net/, providing a discussion forum, announcements, and document sharing among Java Data Mining users.
