From the project website (accessed 25-09-25):
- The Classical Language Toolkit (CLTK) offers natural language processing (NLP) support for the languages of Ancient, Classical, and Medieval Eurasia. Greek and Latin functionality are currently most complete. The goals of the CLTK are to:
- compile analysis-friendly corpora;
- collect and generate linguistic data;
- act as a free and open platform for generating scientific research.
It is a Python package which in some areas extends the Python Natural Language Toolkit (NLTK).
