Define ambiguity and parsing and give one short worked example.

# Ambiguity and Parsing ## Definitions **Parsing** is the process of analyzing a string of symbols (words, tokens, etc.) according to the rules of a formal grammar to determine its structure. **Ambiguity** occurs when a string can be parsed in more than one way—that is, when there are multiple valid parse trees or structural interpretations for the same input. ## Worked Example **Sentence:** "I saw the man with the telescope" This sentence is ambiguous and can be parsed two ways: ### Parse 1: The telescope is the instrument used for seeing ``` [Sentence] | [I] [saw] [NP: the man with the telescope] | [the man] [with the telescope] ``` *Meaning: I used a telescope to see the man* ### Parse 2: The telescope is possessed by the man ``` [Sentence] | [I] [saw] [NP: the man] [PP: with the telescope] | | [the man] [with the telescope] ``` *Meaning: I saw a man who had a telescope* The phrase "with the telescope" can attach to either the verb "saw" (as an instrument) or to the noun phrase "the man" (as a modifier), creating two distinct parse trees and meanings.
