Sample Code

import nltk
from nltk.corpus import stopwords
from nltk.tokenize import word_tokenize

# Download stopwords from NLTK
nltk.download('punkt')
nltk.download('stopwords')

def preprocess_text(text):
    # Tokenization and lowercasing
    tokens = word_tokenize(text.lower())
    # Removing stopwords
    filtered_tokens = [word for word in tokens if word not in stopwords.words('english')]
    return set(filtered_tokens)

def check_plagiarism(text1, text2):
    # Preprocess both texts
    set1 = preprocess_text(text1)
    set2 = preprocess_text(text2)
    
    # Calculate intersection and union
    intersection = set1.intersection(set2)
    union = set1.union(set2)
    
    # Jaccard similarity
    similarity = float(len(intersection)) / len(union)
    return similarity

# Example usage
text1 = "This is a sample text for plagiarism checking."
text2 = "This is a sample text used for checking plagiarism."

similarity_score = check_plagiarism(text1, text2)
print(f"Plagiarism Similarity Score: {similarity_score}")
