Simple Summary

This project aims to analyze content from 100,000 blog URLs using Gemini AI, focusing on extracting plain text from HTML and storing it in MySQL for comprehensive content analysis and fact-checking.

Product Requirements Document (PRD)

Goals:

  • Extract main body content from 100,000 blog URLs
  • Store plain text content in MySQL database
  • Analyze content using Gemini AI for fact-checking and contradiction detection
  • Provide insights on content across multiple websites

Target Audience:

  • Content researchers
  • Data analysts
  • Fact-checkers
  • Digital marketers

Key Features:

  1. HTML to plain text conversion
  2. Efficient MySQL storage for large-scale content
  3. Integration with Gemini AI for advanced content analysis
  4. Query system for selective content retrieval and analysis
  5. Scalable architecture to handle 100,000 URLs

User Requirements:

  • Ability to import and process large sets of blog URLs
  • Simple interface to query stored content
  • Customizable analysis parameters for Gemini AI
  • Reporting system for analysis results

User Flows

  1. URL Import and Processing: User uploads list of URLs -> System extracts main body content -> Content is stored in MySQL

  2. Content Analysis: User selects analysis criteria -> System retrieves relevant content from MySQL -> Gemini AI analyzes content -> Results are presented to user

  3. Custom Query: User inputs specific question or topic -> System retrieves relevant content -> Gemini AI processes query -> User receives targeted insights

Technical Specifications

  • Language: Python 3.9+
  • Database: MySQL 8.0
  • Web Scraping: BeautifulSoup4 (for HTML parsing)
  • AI Integration: Google Gemini API
  • Web Framework: Flask (for potential web interface)
  • ORM: SQLAlchemy
  • Async Processing: Celery with Redis (for handling large-scale processing)
  • Testing: pytest
  • Logging: Python's built-in logging module

API Endpoints

  1. POST /api/import-urls
    • Import list of URLs for processing
  2. GET /api/content/{id}
    • Retrieve specific content by ID
  3. POST /api/analyze
    • Trigger content analysis with specific parameters
  4. GET /api/results/{analysis_id}
    • Retrieve analysis results

Database Schema

Table: blog_content

  • id (INT, PRIMARY KEY)
  • url (VARCHAR(255))
  • content (TEXT)
  • extracted_at (DATETIME)
  • last_analyzed (DATETIME)

Table: analysis_results

  • id (INT, PRIMARY KEY)
  • content_id (INT, FOREIGN KEY)
  • analysis_type (VARCHAR(50))
  • result (TEXT)
  • analyzed_at (DATETIME)

Implementation Plan

  1. Set up project structure and install dependencies
  2. Implement content extraction service using BeautifulSoup4
  3. Set up MySQL database and implement database service
  4. Develop Gemini AI integration service
  5. Create API endpoints for content import, retrieval, and analysis
  6. Implement asynchronous processing with Celery for handling large-scale operations
  7. Develop query system for selective content retrieval
  8. Create basic web interface for easy interaction (optional)
  9. Implement logging and error handling
  10. Write unit and integration tests
  11. Perform system testing and optimization

Deployment Strategy

  1. Set up a scalable cloud environment (e.g., AWS, GCP)
  2. Use containerization (Docker) for consistent deployment
  3. Implement a CI/CD pipeline (e.g., GitLab CI, GitHub Actions)
  4. Deploy MySQL database on a separate, optimized instance
  5. Use a load balancer for distributing incoming requests
  6. Set up monitoring and alerting (e.g., Prometheus, Grafana)
  7. Implement regular backups for the database
  8. Use environment variables for sensitive configuration
  9. Perform staged rollouts (dev, staging, production)
  10. Implement auto-scaling for handling variable loads

Design Rationale

The system is designed to handle large-scale content processing efficiently. Python is chosen for its rich ecosystem in data processing and AI integration. MySQL provides a robust, scalable solution for storing large amounts of text data. The modular structure allows for easy maintenance and future expansions. Asynchronous processing with Celery ensures the system can handle the large volume of URLs without bottlenecks. The integration with Gemini AI leverages cutting-edge natural language processing for sophisticated content analysis, while the API-based design allows for flexible integration with other systems or interfaces in the future.
