## DeepFactAI: Introduction to the Real-Time Fake News Detection System Integrating LSTM and BERT

In the era of information explosion, fake news poses a serious threat to society. DeepFactAI is a deep learning-based fake news detection platform that integrates the dual-model architecture of LSTM (capturing long-distance dependencies) and BERT (understanding contextual semantics) to achieve high-precision real-time analysis, support interpretability analysis and model comparison, and provide technical solutions for information authenticity verification.

## Background and Problem Definition: Challenges in Fake News Detection

The proliferation of fake news has become a global social problem. Traditional rules or shallow machine learning methods are difficult to deal with complex fraud techniques. DeepFactAI directly addresses these challenges, aiming to build an intelligent system that can both accurately identify fake news and provide interpretability analysis.

## System Architecture and Technical Implementation: Dual-Model and Interpretability Design

### Frontend and Backend Architecture
Adopts a separate frontend-backend design: the backend provides high-performance APIs based on FastAPI, and the frontend uses Next.js and React to create smooth interactions.

### Dual-Model Detection Mechanism
- LSTM: Two-layer structure + attention mechanism, GloVe word embedding (300 dimensions), sequence length of 128 tokens, capturing temporal features.
- BERT: Fine-tuned based on bert-base-uncased, processes 512 tokens, excels at complex context understanding. Both models are trained independently, using AdamW optimizer and learning rate scheduling.

### Interpretability Analysis
Introduces LIME technology: by generating perturbed samples to fit local linear models, extracting feature importance, highlighting keywords and weights that affect decisions, enhancing user trust and assisting in review.

## Performance Evaluation: Model Accuracy and Effect of Integration Strategy

Test set performance: LSTM has an accuracy of about 92%, with precision, recall, and F1 all around 90%; BERT achieves an accuracy of 95%, with all metrics in the range of 94-95%. The system supports integrated prediction, balancing the bias of a single model through weighted voting to improve detection reliability.

## Deployment Solutions and Application Scenarios

Supports Docker containerized deployment and one-click deployment on the Vercel cloud platform. Provides RESTful API interfaces (single model prediction, model comparison, health check, etc.), with responses including prediction results, confidence levels, and word importance analysis; it can also be used directly through the frontend interface for interactive detection, facilitating integration into one's own system or direct use.

## Limitations and Future Outlook

Current limitations: Only supports English text detection, cannot handle images or videos, and requires continuous data feedback and model retraining. Future directions: Multilingual support, integrated analysis of multimedia content, deep integration with fact-checking databases, to become a more comprehensive information verification tool.

## Conclusion: The Significance of Technology in Combating Information Pollution

DeepFactAI applies cutting-edge deep learning technology to fake news detection, provides a complete solution, and is open-sourced to promote community progress, which has important practical significance in the long-term battle against information pollution.
