Write an AI to parse sentences and extract noun phrases, using the context-free grammar formalism and the Python nltk library. A common task in natural language processing is parsing, the process of determining the structure of a sentence.
A common task in natural language processing is parsing, the process of determining the structure of a sentence. This is useful for a number of reasons: knowing the structure of a sentence can help a computer to better understand the meaning of the sentence, and it can also help the computer extract information out of a sentence.

Parser (Context-Free Grammar) see directory. The assignment is about parsing a sentence to determine its structure. First, the task requires pre-processing the sentence to convert it into a list of words. Second, the task requires a set of context-free grammar rules on how sentences can be structured (the most challenging part)
