← Language & CommunicationWhy does a statistical parser, employed in computational linguistics, sometimes select an incorrect parse tree for a grammatically valid sentence?
A)Insufficient feature set generalization occurs
B)Probabilistic dominance outweighs structural constraints✓
C)Lexical category ambiguity is resolved efficiently
D)Syntactic dependencies ensure total coverage
💡 Explanation
A statistical parser chooses parse trees based on probabilities learned from training data. Because probabilistic dominance can override actual grammatical structure when observed frequencies skew the parser's preference, therefore, an incorrect tree may result, rather than one strictly based on syntax.
