PDF Similarity Checker

This Python script is designed to compare the text content of two PDF files and determine their similarity using the Jaccard index.

Requirements

• Python 3.6 or higher
• PyPDF2
• NLTK

Usage

1. Place the two PDF files that you want to compare in the same directory as the Python script.
2. Name the PDFs as 1.pdf and 2.pdf
3. Open a terminal window and navigate to the directory containing the script and PDF files.
4. Run the script using the following command: python main.py
5. The script will output the Jaccard similarity index as a percentage.

Notes

• Its reccommended to uncomment line 9 and 10 on the first run.
• The script assumes that the text content of the PDF files is in English.
• The script removes stop words and non-alphanumeric characters from the PDF text before performing the similarity check.
• The script does not take into account formatting, layout, or images in the PDF files.
• The script assumes that you've named your PDFs as 1.pdf and 2.pdf.
