Plagiarism Detection Script

This Python script performs plagiarism detection on a set of text documents using the Term Frequency-Inverse Document Frequency (TF-IDF) approach. It calculates the cosine similarity between pairs of documents to identify potential cases of plagiarism.

Usage

  1. Place the text documents (.txt files) in the same directory as the script.

  2. Run the script:

    python plagiarism_detection.py

  3. The script will output pairs of documents along with their cosine similarity scores, indicating potential plagiarism.

Requirements

Make sure to install the required dependencies before running the script:

pip install scikit-learn

How it works

  • The script reads all .txt files in the current directory and stores their content in a list (student_notes).
  • It then vectorizes the text using the TF-IDF vectorizer from scikit-learn.
  • Cosine similarity is calculated between each pair of documents to identify potential plagiarism.
  • The script outputs pairs of documents along with their cosine similarity scores.
