Knowledge Representation
important attribute : isa and instance
relationship among attributes
at what level of detail should the world be represented?
Mary is Sue’s cousin. เมรี่��เป็�นหลานของซู�Mary = daughter(brother(mother(Sue)))
Mary = daughter(sister(mother(Sue)))
Mary = daughter(brother(father(Sue)))
Mary = daughter(sister(father(Sue)))
Mary = daughter(sibling(parent(Sue)))
