S.C. Shapiro
Understand and communicate in English;
Discuss specific, generic, and “rule-like” information;
Reason;
Discuss acts and plans;
Sense;
Act;
Maintain a model of itself;
Remember and report what it has sensed and done.
Cassie
• A computational cognitive agent
– Embodied in hardware
– or Software-Simulated
– Based on SNePS and GLAIR.
S.C. Shapiro
SNePS
• Knowledge Representation and Reasoning
– Propositions as Terms
• SNIP: SNePS Inference Package
– Specialized connectives and quantifiers
• SNeBR: SNePS Belief Revision
• SNeRE: SNePS Rational Engine
• Interface Languages
– SNePSUL: Lisp-Like
– SNePSLOG: Logic-Like
– GATN for Fragments of English.
