We are excited to release the improved Carmen Twitter geotagger, Carmen 2.0! We have implemented the following improvements:
- A new location database derived from the open-source GeoNames geographical database. This multilingual database improves the coverage and robustness of Carmen as shown in our analysis paper "Changes in Tweet Geolocation over Time: A Study with Carmen 2.0".
- Compatibility with Twitter API V2.
- An up to 10x faster geocode resolver.
