In feature comparison models, the ___ features are specific to a concept (e.g., a robin has feathers) and the ___ features are descriptions that are common to multiple concepts but not necessarily essential (e.g., a robin perches in trees).

Question

BlackTom AI · Accepted Answer

In feature comparison models, terms distinguish between features tied to a specific concept and those that are more general.
Option 1: defining; characteristic. This pairing makes sense because defining features are the essential, concept-specific attributes (such as a robin having feathers), while characteristic features are descriptions common across many concepts but not strictly essential (like perching in trees). This aligns with typical feature taxonomy in concept representations.
Option 2: characteristic; defining. Reversing the roles would imply that general, non-essential features are defining the concept, which is incorrect because defining features are the core, necessary attributes that distinguish the concept.
Option 3: defining; property. Here the second term uses 'property' rather than the more typical 'characteristic' for non-essential, cross-concept features. While plausible in some vocabularies, the standard pairing in this context is defining and characteristic, so this choice is less accurate.
Option 4: characteristic; property. This option swaps both terms and uses 'property' instead of 'defining' for the first slot; it inaccurately assigns non-essential features as the defining elements and uses an alternative term for the second slot, making it inconsistent with the conventional terminology described.

In feature comparison models, the _ features are specific to a concept (e.g., a robin has feathers) and the _ features are descriptions that are common to multiple concepts but not necessarily essential (e.g., a robin perches in trees).单项选择题
