1. Examples of knowledge representation formalisms include semantic nets, frames, rules, and ontologies. 2. Frames are also an extensive part of knowledge representation and reasoning schemes. 3. Rule-based systems provided acceptable computational efficiency while still providing powerful knowledge representation . 4. Another area of knowledge representation research was the problem of common sense reasoning. 5. A further example of SHYSTER s pragmatism is its simple knowledge representation structure. 6. The semantic network of knowledge representation systems has been studied in various paradigms. 7. Knowledge representation and reasoning are a key enabling technology for the Semantic web.8. ". . the fields of knowledge representation and natural language .. 9. A "'frame language "'is a technology used for knowledge representation in artificial intelligence. 10. He is particularly famous for his contributions to planning, knowledge representation , and robotics.
