Generality and Subsumption

• Inheritence is intimately related to generality and subsumption.
• The eat frame is more general than the eat-chinese frame. Why?
• There are fewer constraints on it. Eat-chinese is still an eat, but there are eats that are not eat-chinese (e.g. eat-Italian)
• Eat subsumes eat-chinese.
• What are the constraints on eat-chinese that are not on eat?
• How do defaults effect this subsumption? Can you eat-chinese with a fork?
• What about things that break the essential character of an object? E.g. toy-dog and dog? Is there an example for eating?
