Abstract:

Research performed on the Command Action Team CAT system and the Smart Knowledge Acquisition Tool SKAT is described. CAT is a rule-based expert system to perform threat assessment in the naval domain SKAT is an automated knowledge acquisition tool for CAT. These systems were developed jointly by Naval Ocean Systemns Center and Carnegie Mellon University. The research explored an alternative knowledge representation scheme for CAT that reduced the number of working memory elements. A knowledge representation mechanism was developed to investigate the feasibility of incorporating higher-level control on rule-firings based on the idea of an experts problem-solving method. A system is described for automatically generating OPS83 rules from an external database, and an analysis is performed describing SKATs ability to generate the CAT system. Keywords Artificial intelligence, Real time.
