Responding to this problem, the Defense Advanced Research Projects Agency (DARPA) has sponsored a sequence of two programs for the development of the second generation of knowledge-based systems science and technology: (1) the High-Performance Knowledge Bases Program (HPKB FY97-99) and (2) the Rapid Knowledge Formation Program (RKF FY00-03).(1,2) The goal of the HPKB Program was to produce the technology needed to enable system developers to rapidly construct large knowledge bases that provide comprehensive coverage of topics of interest, are reusable by multiple applications with diverse problem-solving strategies, and are maintainable in rapidly changing environments.
The HPKB Program emphasized the development of very large knowledge bases by knowledge engineers, demonstrating the utility of large knowledge bases and the feasibility of large-scale reuse.
RKF is organized in a manner similar to HPKB, with challenge problems administered by an evaluation contractor (IET assisted by Veridian Pacific-Sierra Research (PSR) and George Mason University Institute for Biosciences, Bioinformatics, and Biotechnology) as a basis for formal evaluation of the technology provided by the developers.
The developed tool, called DISCIPLE-COA, is an important result of the HPKB Program that is representative of the many accomplishments of the program.

HPKB challenges the research community to share, merge, and collectively develop large ontologies for significant military problems.
HPKB encompasses work on a variety of logical, probabilistic, and other inference methods.
Because HPKB is grounded in domain-specific tasks, the focus of much ontological engineering is this middle layer.
The HPKB participants are organized into three groups: (1) technology developers, (2) integration teams, and (3) challenge problem developers.
A programmatic innovation of HPKB is challenge problems.
The HPKB challenge problems are designed to support new and ongoing DARPA initiatives in intelligence analysis and battlespace information systems.
The challenge problem development team worked with GENOA representatives to identify areas for the application of HPKB technology.
