Why should I describe myself to a computer??!! How will it understand what I say? Structural ambiguity exists when the syntactic structure of a sentence or fragment of language is in question. The sentence ''I ate chicken with a fork'', could mean, to a computer, either that I used a fork to eat the chicken, or that the chicken had a fork.Let us assume that the computer seeks to understand the text input. The process of ''understanding'' a piece of text involves passing it through various stages of linguistic processing, including word-level, syntactic, and semantic analysis. A syntactic analysis shows that the sentence ''My favourite song is - I shot the sheriff'' is a declarative sentence containing a noun phrase, an adjective, another noun, a hyphen, then another noun, a verb, another noun phrase, and finally a punctuation character.Most systems place restrictions on how the input is analyzed. And if I am unlucky, that sentence can lead the CIA to hold me as a terror suspect. It may be many years before your computer understands all of the nuances of human communication. A Mr.Language-ROBOT character, operating on logic and blissfully unaware of emotion and inflection, would never guess that the statement, ''Where were you last night?'' was not just a request for temporal location, but a red flag telling the listener that he was in deep trouble. So, until the computer evolves to a higher level of understanding, I'm not describing myself to a machine!!!. Compounded Annually!!!
