Reference: QAnything

1. Task Management

   • Deploy a task manager to handle the distribution of crawling jobs.
   • Ensure tasks are evenly distributed across available resources to prevent bottlenecks.
   • Use a robust queue system to prioritize tasks, manage retries, and monitor the crawling process.

2. Content Extraction with Playwright-Python and OCR

   • Employ Playwright for Python to automate and control browser environments for scraping dynamic web pages that rely on JavaScript.
   • Integrate OCR technology to recognize and extract text from images and other irregular content types that cannot be easily selected.

3. Page Classification

   • Analyze the structure of the data stored and classify pages accordingly.
   • Use machine learning or heuristic methods to categorize pages for targeted data extraction.
