### **Content Processing**

Galaxy processes Wikipedia content with:

* **Text extraction**: Extracts article body text, preserving section structure and headings
* **Content normalization**: Normalizes content for consistency across sources
* **Entity extraction**: Automatically extracts and normalizes semantic entities including:
  * Dates and times (normalized to standard formats)
  * Email addresses and URLs
  * Measurements, money, and percentages
  * Serial numbers and version numbers
  * Technical measurements (temperature, pressure, voltage, current, frequency)
