Modeling complex phenomena such as food insecurity requires reasoning over multiple levels of abstraction and fully utilizing expert knowledge about multiple disparate domains, ranging from the environmental to the sociopolitical.

Delphi is a Python/C++ library for assembling causal, dynamic, probabilistic models from information extracted from two sources:

Delphi builds upon INDRA and Eidos.

For a detailed description of our procedure to convert text to models, see this document.

Delphi is also part of the AutoMATES project.
