Fake news detection using machine learning source code Sometimes, we have too much information and don’t know what is true or false. Fake news is when people lie or make mistakes on the internet. Fake news can make people confused or angry. Technology is getting better and brighter. It can help us find out what is fake and what is real. This article discusses fake news and how technology can help us stop it.I will also provide source code for it, which you can use to make your own Fake news detection system using machine learning. Fake News Detection Using Machine Learning We want to know what’s real and what’s not. We have an intelligent system that can read text (like a message, tweet, or news story) and let us know how likely it is to be fake. The system is unique because it sees a lot of real and fake news from many different places and ways. Based on what it learned, the system can answer each word with either “yes” or “no.” It can’t read words like we can. There must be numbers. So, we must find ways to turn the words into numbers. After that, we can use Naive Bayes, Logistic Regression, and Random Forests to teach the system and check its performance.These algorithms must work better sometimes for the system to learn well. After that, we can use more complex methods like Attention or LSTM. These ways can help the computer read the words better. Fake news detection using machine learning source code To develop a fake news detection using machine learning, follow these steps. Download Fake news detection datasets Step 1: Download the dataset This folder contains 2 datasets. One is for fake news, and the other is for actual news. The folder size is 43MB; you can download it here. Step 2: Folder Structure Extract both datasets and place them in the new folder. In the new folder, make a python file and open it with Vs. Code.The extenstion of file should be .py Step 3: Import required libraries import pandas as pd from sklearn.model_selection import train_test_split from sklearn.feature_extraction.text import TfidfVectorizer from sklearn.naive_bayes import MultinomialNB from sklearn.pipeline import make_pipeline from sklearn.metrics import accuracy_score, classification_report import pandas as pd from sklearn.model_selection import train_test_split from sklearn.feature_extraction.text import TfidfVectorizer from sklearn.naive_bayes import MultinomialNB from sklearn.pipeline import make_pipeline from sklearn.metrics import accuracy_score, classification_report Step 4: Load both datasets Load both datasets using the pandas library and label them 0 and 1. For True new, label it as 0, and For Fake news, label it as 1 # Load true news dataset true_df = pd.read_csv('True.csv') true_df['label'] = 0 # Add a label column for true news # Load fake news dataset fake_df = pd.read_csv('Fake.csv') fake_df['label'] = 1 # Add a label column for fake news # Load true news dataset true_df = pd.read_csv('True.csv') true_df['label'] = 0 # Add a label column for true news # Load fake news dataset fake_df = pd.read_csv('Fake.csv') fake_df['label'] = 1 # Add a label column for fake news Step 5: Combine both datasets # Combine the datasets df = pd.concat([true_df, fake_df], ignore_index=True) # Combine the datasets df = pd.concat([true_df, fake_df], ignore_index=True) Step 6: Split the data into training and testing sets # Split the data into training and testing sets X_train, X_test, y_train, y_test = train_test_split(df['text'], df['label'], test_size=0.2, random_state=42) # Split the data into training and testing sets X_train, X_test, y_train, y_test = train_test_split(df['text'], df['label'], test_size=0.2, random_state=42) Step 7: Train the Model model = make_pipeline(TfidfVectorizer(), MultinomialNB()) model.fit(X_train, y_train) model = make_pipeline(TfidfVectorizer(), MultinomialNB()) model.fit(X_train, y_train) Step 8: Make predictions and Evaluate the model # Make predictions on the test set predictions = model.predict(X_test) # Evaluate the model accuracy = accuracy_score(y_test, predictions) classification_report_result = classification_report(y_test, predictions) # Make predictions on the test set predictions = model.predict(X_test) # Evaluate the model accuracy = accuracy_score(y_test, predictions) classification_report_result = classification_report(y_test, predictions) Step 9: Display results # Display the result print(f'Accuracy: {accuracy}') print('Classification Report:n', classification_report_result) # Display the result print(f'Accuracy: {accuracy}') print('Classification Report:n', classification_report_result) Step 10: User Input By adding this step we can give input of our choice give input from the list of datasets it will tell if the news is fake or true Take input from the user user_input = input("Enter a news article: ") # Make a prediction prediction = model.predict([user_input]) # Display the result if prediction[0] == 0: print("The news is likely to be true.") else: print("The news is likely to be fake.") Take input from the user user_input = input("Enter a news article: ") # Make a prediction prediction = model.predict([user_input]) # Display the result if prediction[0] == 0: print("The news is likely to be true.") else: print("The news is likely to be fake.")

While machine learning greatly improves fake news identification, complete elimination remains a difficult task. Human interaction and critical thinking are necessary when working with machine learning algorithms. How frequently do machine learning models need to be updated for fake news detection? Machine learning models should be updated on a regular basis to reflect changing language trends and new methods used by fake news publishers. Continuous learning is crucial. Can individuals contribute to fake news detection? Yes, individuals play an important role as key users of knowledge. Reporting suspicious content and improving media literacy are helpful approaches to help struggle false news.
