A Rapid Fake News Detection Model for Cyber Physical Social Services Using Deep Learning

Abstract

With the prevalence of social network service in cyber-Physical space, flow of various fake news has been a rough issue for operators of social service. Although many theoretical outcomes have been produced in recent years, they are generally challenged by processing speed of semantic modeling. To solve this issue, this paper presents a deep learning-based fast fake news detection model for cyber-physical social services. Taking Chinese text as the objective, each character in Chinese text is directly adopted as the basic processing unit. Considering the fact that the news are generally short texts and can be remarkably featured by some keywords, convolution-based neural computing framework is adopted to extract feature representation for news texts. Such design is able to ensure both processing speed and detection ability in scenes of Chinese short texts. At last, some experiments are conducted for evaluation on a real-world dataset collected from a Chinese social media. The results show that the proposal possesses lower training time cost as well as higher classification accuracy compared with baseline methods.

Introduction

Introduction:

The rise of social media has increased the speed and reach of information dissemination, but it has also led to the rapid spread of fake news. Fake news can cause public panic, misinformation, policy disruption, and societal unrest. Traditional fact-checking methods are slow and ineffective at scale, creating the need for automated detection systems.

Problem Statement:

Fake news threatens the integrity of cyber-physical social systems (CPSS), affecting public perception, health, economy, and stability. Rapid, scalable, and accurate detection mechanisms are essential.

Literature Review:

• Traditional methods: Rule-based and statistical models (e.g., keyword detection, sentiment analysis) are limited in adaptability.

• Machine Learning: SVMs, Decision Trees, Naïve Bayes offer moderate success but rely heavily on handcrafted features.

• Deep Learning: CNNs, RNNs, LSTMs, and especially transformer models (like BERT) have significantly improved fake news detection through better contextual understanding.

• Limitations: Existing systems struggle with dataset bias, real-time processing, and adversarial tactics.

Proposed Methodology:

A hybrid deep learning model is developed, combining:

• CNNs: For feature extraction

• BiLSTMs: For capturing context in sequences

• Transformers (BERT): For understanding complex language semantics

• Multimodal input: Includes text, image metadata, and user interaction data

Pipeline:

1. Dataset: LIAR, FakeNewsNet, real-time social media data

2. Preprocessing: Tokenization, stop-word removal, stemming, lemmatization

3. Feature Representation: Word embeddings (Word2Vec, GloVe, BERT)

4. Model Training: Transfer learning, fine-tuning, hyperparameter optimization

5. Real-Time Deployment: Cloud-based stream processing for scalability

Objectives:

• Develop a real-time fake news detection system for CPSS

• Achieve high accuracy (95%+)

• Improve contextual comprehension using BERT

• Evaluate against baseline models

• Enable practical deployment on social media and digital platforms

Experimental Setup & Evaluation:

• Data split: 80% training, 10% validation, 10% testing

• Metrics used: Accuracy, precision, recall, F1-score, AUC-ROC

• Model interpretation: Explainable AI methods (e.g., SHAP values)

• Comparison: Outperforms traditional ML and earlier DL models

Results & Discussion:

• Accuracy: 95%+ fake news classification

• Performance: BERT-based models surpass CNNs and traditional methods

• Multimodal inputs: Enhance precision and reduce false positives

• Scalability: Suitable for high-volume, real-time social media monitoring

• Robustness: Strong against adversarial misinformation strategies

Ethical Considerations:

A related survey explored how internet chatting affects students’ academic engagement. A structured questionnaire assessed usage patterns and learning impacts, ensuring a holistic view of online platform influence on education.

Conclusion

This study presents a novel deep learning-based framework for rapid fake news detection in CyberPhysical Social Services. By integrating CNNs, BiLSTMs, and transformer architectures, our model achieves high classification accuracy while maintaining computational efficiency. Future research will explore multimodal analysis, incorporating images, videos, and metadata to further enhance detection capabilities. Additionally, integrating explainability mechanisms will improve model interpretability, fostering greater trust in automated misinformation detection systems. By integrating CNNs, BiLSTMs, and transformer architectures, our model achieves high classification accuracy while maintaining computational efficiency. Future research will explore: 1) Multilingual Fake News Detection: Expanding model adaptability to diverse languages. 2) Explainability Mechanisms: Improving transparency in deep learning predictions. 3) Cross-Platform Generalization: Enhancing model robustness across different social media ecosystems.
