Reddit Fact-Checking Tool: Using Machine Learning to Identify Misinformation in Social Media

reddit-factuality-detection is a machine learning-based fact-checking tool for Reddit posts. It uses Transformer models like BERT and DistilBERT, combined with the FACTOID and Reuters datasets, to help users identify the authenticity of social media content. This tool aims to address the challenge of misinformation spread in the era of information explosion, and is applicable to scenarios such as personal verification, content moderation, education, and research. It is a practical tool for using technology to combat misinformation.

In the era of information explosion, social media platforms like Reddit generate massive amounts of content, but misinformation spreads faster than the truth, posing a severe challenge to personal decision-making and public discourse.

reddit-factuality-detection is an open-source project focused on fact-checking Reddit posts. It combines traditional machine learning with Transformer models (BERT/DistilBERT), and its data sources are FACTOID and Reuters verified data, ensuring sample diversity to enhance generalization ability.

Data Preprocessing

Prepare text data through processes such as word segmentation, stopword removal, and feature extraction.

Model Strategy

• Traditional algorithms: Baseline screening with strong interpretability;
• Transformer models: Core component, BERT/DistilBERT capture deep semantics and better understand complex text structures.

Dual data sources ensure the diversity of model training samples. Results are presented intuitively: marking true/false + contextual explanation, with a transparent design to help users understand the AI decision-making process.

Application Scenarios:

• Individual users: Verify suspicious content;
• Content moderation: Assist administrators in identifying misinformation;
• Education: Teaching tool;
• Research: Provide data support.

The model is not perfect and may have errors. It is recommended that users combine context, cross-verify from multiple sources, and use technology as an auxiliary decision-making tool without replacing human critical thinking.

The project is open-source under the MIT license, and community contributions are welcome. This tool is an attempt to use technology to combat misinformation, providing users with a self-protection tool that is worth exploring and contributing to.
