Document Summary

Plato, leibiz, descartes, fodor: concepts like justice and knowledge are innate/ not directly learned (rationalism: matching new views to innate views to form new concepts. Locke, hume: concepts are learned through sensory experience (empiricism: closer to our intuitive understanding of concepts. If x is intelligent then x has property y: property y is necessary. If x has property y, then x is intelligent: property y is sufficient. Frames, schemas, scripts: concepts as representations of typical entities or situations. Hierarchical information: kind hierarchies, isa hierarchies, part hierarchies. Hierarchies easily support inheritance; information about subtypes can be inherited from super types and does not need to be restated. Spreading activation in networks is another way to think about information flow (as associations) Concepts support generalization to new instances though matching and inference. A concept can be classified as a subtype of a more general concept by matching against at least one slot.
