This project utilizes a context-free grammar (CFG) ruleset implemented with the Natural Language Toolkit (NLTK) to break down the structure of sentences and extract noun chunks. By defining grammar rules that capture the syntactic patterns of noun phrases, the project enables the identification and extraction of noun chunks from natural language text, facilitating deeper linguistic analysis and information extraction.
You'll need to have Python and pip3 installed. You can download them from the official Python website.
- Clone the repository:
git clone https://github.com/ColinDao/buffalo.git- Navigate to the project directory:
cd buffalo- Install the required dependencies:
pip3 install -r requirements.txtTo execute the parser, run the following command:
python parser.py [1.txt]Watch as the parser is able to deconstruct and visualize the text as well as pull out key noun phrases!
CFG Definition: Define a set of context-free grammar rules that describe the syntactic structure of noun phrases,
including rules for determiners, adjectives, nouns, and more.
Tokenization: Using regular expressions, gather all of the elements of the sentence.
Parsing Algorithm: Implement a parsing algorithm using NLTK to parse sentences according to the defined CFG ruleset,
identifying and extracting noun chunks using depth-first search based on the parsed syntactic structure.
Language: Python
Libraries: NLTK, Sys, RE
This project was completed as a part of CS50's Introduction to Artificial Intelligence with Python. Go check them out!
