Fake news spreads like wildfire in today’s fast-paced digital world 🌐, often distorting public perception and influencing opinions. As social media and online platforms become the primary sources of information for millions of people, the spread of misinformation has become a pressing concern
This project focuses on classifying news by type and label using a source-based approach 🧑💻, which involves analyzing key source information such as the author ✍️, publication date 📅, and the reputation of the source itself 🏅. By leveraging structured data and machine learning techniques 🤖, we aim to create an automated system that can efficiently identify and classify news articles based on their authenticity ✅.
Our goal is to provide a reliable method for distinguishing between real and fake news 🔍, contributing to the fight against misinformation. This system not only helps improve news credibility but also empowers users with the tools needed to critically assess the information they consume, promoting a more transparent and trustworthy online news environment 🌍.
Through this project, we hope to raise awareness of the importance of verifying sources ✅ and foster the development of applications that can assist in combating fake news, ultimately paving the way for more informed, educated, and responsible news consumption in the digital age 📚.

Social media platforms are a treasure trove of content, with news being one of the most consumed categories. However, not all news is authentic. Fake news, whether posted by politicians, news outlets, or civilians, can have far-reaching consequences.
Challenges:
- Manual classification of news is time-consuming and prone to bias.
- Verifying authenticity remains a critical task in the fight against misinformation.
Published paper: Source-Based Fake News Classification
- Preprocessed data from the Getting Real about Fake News dataset.
- Eliminated skew for improved reliability.
- Comprehensive inclusion of source information, including author names, publication dates, and labels.
In an age where fake WhatsApp forwards and misleading Tweets influence public opinion, it’s crucial to develop tools to:
- Mitigate the spread of misinformation.
- Inform users about the nature of the news they consume.
This project’s inspiration lies in creating:
- Practical applications to analyze and classify news articles.
- Plugins and tools for easy access to fact-checking.
- Awareness campaigns about the consequences of consuming and spreading fake news.
- Source-Based Labeling: Ensures credibility by tracking the origin of news articles.
- Automation: Reduces human bias in classification.
- Informed Consumption: Helps users make smarter decisions about the news they trust.
In this project, two machine learning approaches are evaluated for classifying fake news:
- RandomForestClassifier using TF-IDF
- Embeddings + CNN (Convolutional Neural Networks)
-
TF-IDF (Term Frequency-Inverse Document Frequency) is a traditional text preprocessing technique that transforms text data into a high-dimensional sparse vector space. This method measures the importance of a word in a document relative to its frequency across all documents.
-
The RandomForestClassifier then uses this vectorized representation for classification. Random forests are an ensemble method that builds multiple decision trees and combines their outputs, typically resulting in a strong and reliable classifier.
Pros:
- Efficient and works well for smaller datasets.
- Simple to implement and interpret.
Cons:
- The sparse representation of text doesn’t capture the semantic meaning of words or their contextual relationships.
- May struggle with large datasets or when the relationships between words are complex.
-
Embeddings are dense, lower-dimensional vector representations of words that capture their semantic meaning. By mapping words with similar meanings closer together in a vector space, embeddings provide more context and depth compared to traditional vectorization methods like TF-IDF.
-
The CNN architecture is well-suited for text classification tasks. In this case, convolutional layers capture local patterns in the text, and pooling layers help reduce dimensionality. CNNs can learn more abstract and hierarchical features from text, which is useful in identifying subtle patterns and relationships that might indicate whether news is fake or real.
Pros:
- Better at capturing semantic relationships and context of words.
- Suitable for large and complex datasets with nuanced patterns.
- Can provide higher performance in text classification tasks.
Cons:
- Requires larger datasets for training.
- Needs more computational resources and may take longer to train.
- Both approaches were trained and evaluated on the Getting Real about Fake News dataset.
- The RandomForestClassifier using TF-IDF showed decent performance for basic tasks but struggled to capture deeper semantic meaning and context.
- The Embeddings + CNN approach outperformed the traditional method in both training and testing accuracy, as it was able to better capture the relationships between words and classify news more effectively.
The results of this comparison highlight the advantages of using Embeddings + CNN for more complex text classification tasks, especially in dealing with large, high-dimensional datasets. However, RandomForestClassifier using TF-IDF remains a useful and simpler tool for tasks where computational resources or training data are limited. This project shows that using a source-based approach combined with machine learning techniques can effectively aid in the detection of fake news.
