PyFCG’s codebase is versioned using Git and distributed under an open source license. Its documentation is available via the Read the Docs platform.

Getting started with PyFCG

PyFCG comes with three walkthrough tutorials that showcase how the library can be integrated in typical use cases of FCG:

• Grammar formalisation and testing
• Learning construction grammars from corpora
• Agent-based models of emergent communication
