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 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.
The representations being developed in HPKB are intended to serve as a crisis corporate memory to help analysts discover historical precedents and analogies for actions.
The second challenge-problem domain for HPKB is battlespace reasoning.
Because HPKB is not concerned with signal processing, the input are not real JSTARS data but are instead generated by a simulator and preprocessed into vehicle tracks.
Model fragments such as these are thought to constitute the knowledge of intelligence analysts and, thus, should be the content of HPKB movement-analysis systems.
