Accepted Answer

To simplify the parsing process by breaking down complex sentences into smaller, manageable units.

Answer

To resolve ambiguity in sentences.

Answer

To improve the accuracy of parsing results by enforcing specific grammatical rules.

Question 10

Question 17

Explain the fundamental difference between top-down and bottom-up parsing techniques:

Accepted Answer

Top-down parsing commences from the root of the parse tree, while bottom-up parsing begins with the leaves.

Answer

Top-down parsing is inherently more efficient than bottom-up parsing.
