This CYK (Cocke-Younger-Kasami) parser is a Python program that demonstrates parsing a sentence using a Context-Free Grammar (CFG) represented in Chomsky Normal Form (CNF). It utilizes the provided Python files and a JSON configuration file to perform the parsing. The CNF conversion is done by the CNFConverter class in chomsky.py, and the CYK parsing is performed in cyk.py.

• main.py: The main Python script that loads the CFG from the input.json file, converts it to CNF, and then performs CYK parsing on a sample sentence.
• chomsky.py: The Python module responsible for the CNF conversion of the provided CFG.
• cyk.py: The Python module that implements the CYK parsing algorithm.
• input.json: The JSON configuration file containing the CFG in CNF format.

To run the CYK parser for the given CFG, follow these steps:

1. Clone this repository to your local machine:

   git clone https://github.com/bl33h/CYK-Parser
   cd src
   python main.py
