← Language & CommunicationWhy does a language acquisition model relying solely on distributional semantics for dictionary creation struggle with polysemous words, even with a large corpus?
A)Limited cross-linguistic transfer learning exists
B)Context vectors smear distinct word senses✓
C)Lexical access times become exponentially long
D)Gradient descent procedures reach local minima
💡 Explanation
Distributional semantics represents words by their context. A single vector for a polysemous word blurs the distinct senses because the mechanism of vector averaging merges different usages into one representation; therefore, the model fails to differentiate senses, rather than because of optimization failures.
