Knowledge Rich Acquisition of Knowledge from Experts Who Are Non-Logicians

The Knowledge Rich Acquisition of Knowledge from Experts Who Are Non-Logicians (KRAKEN) was performed under DARPA's Rapid Knowledge Formation (RKF) Program. The KRAKEN system allows Subject Matter Experts (SMEs) to more easily, efficiently, and correctly enter their knowledge into an artificial intelligence knowledge-based system. KRAKEN's usefulness has been demonstrated in three challenge problems related to molecular biology, authoring of course-of-action critiquing rules (CA) , and terrain analysis. This report contains a description of KRAKEN, a Knowledge Entry system developed as part of the Rapid Knowledge Formation Project, funded by DARPA. In addition to describing the KRAKEN system as it exists today, this report also discusses the development of the system, its performance in three annual evaluations, the lessons learnt that are of general interest to the community of knowledge entry systems developers, and specific insights for future research. The following are goals... (MORE)
