concept ) concept (with fewer attributes) Abstract is de ned as removing an attribute from a concept. The abstract knowledge source makes a concept less speci c by abstracting away an irrelevant detail (see also specify). Abstract may also work on an instance. Classify (set of) attribute(s) ) concept The classify knowledge source takes a number of attributes and classi es these as representing ...

ing Terminate-Conversation to ancestor concept Terminating producing abstract target meaning: (A Terminating3 ( t Terminating) (t erminated3 ( f terminated) (A Computer-Process10 (f Computer-Process)) ) (terminator3 (f terminator) (A I46 ( f I)))) The first step in the processing of a similarity extension inference is to identify the concepts specified in the input example with their correspond...

i.e., the less specific) the object becomes. People may consider concepts in a similar way. That is, the extent to which a concept includes other concepts may determine whether the concept is more or less abstract or concrete. Also, it has been found that whether a concept is superordinate or subordinate is not related to the extent to which the concept activates visual imagery in people’s mind...

We propose a new abstract definition of competitive equilibrium: a profile of alternatives and a public ordering (prestige, price or a social norm) such that each agent prefers his assigned alternative to all lower-ranked ones. The equilibrium operates in an abstract setting built upon a concept of convexity borrowed from Convex Geometry. The "magic" of linear equilibrium prices is put into per...

Abstract concepts are characterized by their underlying structure rather than superficial features. Variation in the examples used to teach abstract concepts can draw attention towards shared structure and away from superficial detail, but too much variation can inhibit learning. The present study tested the possibility that increasing attention to underlying structural relations could alleviat...
