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

• Python 3.6 or higher
• PyPDF2
• NLTK

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.

• 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.
