Background: Trust Crisis in the Information Age

In today's digital age, the spread of fake news and misleading information far outpaces the verification capabilities of traditional media. Users often struggle to judge the credibility of content when browsing news, which not only affects personal decisions but may also pose a threat to social stability. How to use technical means to automatically evaluate the credibility of news articles has become an important application scenario in the field of machine learning.

The project introduced in this article is a complete solution built to address this problem. It is not just a simple classification model, but an end-to-end MLOps system covering data ingestion, feature engineering, model training, inference services, monitoring and alerting, and cloud deployment.

Section 04

System Architecture Overview

The project adopts the FTIM (Feature–Training–Inference–Monitoring) architecture, realizing a complete closed loop from raw data to production-level services:

Section 05

Data Layer

The system integrates multiple data sources:

  • Static Datasets: LIAR Dataset (fact-checking of political statements), FakeNewsNet (real and fake news from PolitiFact and GossipCop sources)
  • Real-Time Data Streams: RSS feeds, NewsAPI (optional), BeautifulSoup web scraping

Section 06

Feature Engineering Layer

Raw text is converted into feature vectors usable by the model through techniques like TF-IDF. It also supports feature storage and version management to ensure consistency between training and inference phases.

Section 07

Model Training Layer

  • Baseline Model: Traditional machine learning model based on Scikit-learn
  • Deep Learning Model: DistilBERT text classification implemented with PyTorch
  • Experiment Tracking: MLflow records hyperparameters, metrics (accuracy, precision, recall, F1 score), and model artifacts

Section 08

Inference Service Layer

  • FastAPI: Provides high-performance RESTful API prediction endpoints
  • Streamlit: Builds a user-friendly visualization interface
  • Response Format: JSON output includes prediction label, confidence, credibility score (0-100), and risk level (low/medium/high)
