The SNePS BDI architecture

Business .ems =':'ynd Monegemen' Most AI systems are effective either for inference or for acting/planning but not for both. The SNePS BDI Tec'-nOIogy architecture uses propositional semantic network representations of beliefs, goals, acts, plans, and a representational 'f concept called transformers. Transformers help capture a unified approach to acting and inference. They can be ,Olio, used to represent reasoning rules, reactive desires, desires for acquiring knowledge, preconditions and effects of :'~I actions as well as plan decompositions. A rational engine module operates on these representations and is responsible for the agent's reasoning and acting behavior. SNeRE, the SNePS rational engine, employs a quasi-con",onlO current message passing scheme, implements the underlying logic as well as the action theory, has forward, backward ~ Science and bidirectional inference and acting. It also incorporates the notions of truth maintenance and spreading ° M5S 1M activation. . damy of Scionce. 18-22
