🌍 Geographic Coordinate Extractor

This Space demonstrates the performance of AI models trained to automate the extraction of geographical coordinates from the 18th-century Encyclopédie of Diderot and d'Alembert.

How it Works:

  1. Classification: A BERT-like model identifies whether a given encyclopedia entry contains geographic coordinates.
  2. Extraction & Normalization: An mT5-based model retrieves raw coordinate strings from the text and normalizes them into a standard DMS format.

You can test the models by entering a custom text or choosing from the examples provided.
