The CLTK relies heavily upon several free open source projects.

• Glottolog (https://glottolog.org/): Language metadata and classification references.
• Stanza (https://stanfordnlp.github.io/stanza/): Neural pipeline components used by many CLTK backends.
• Universal Dependencies (https://universaldependencies.org/): Global language definitions for morphosyntax and syntactic parsing.
