  Models of complicated systems can be represented in different ways - inscientific papers, they are represented using natural language text as well asequations. But to be of real use, they must also be implemented as software,thus making code a third form of representing models. We introduce theAutoMATES project, which aims to build semantically-rich unifiedrepresentations of models from scientific code and publications to facilitatethe integration of computational models from different domains and allow formodeling large, complicated systems that span multiple domains and levels ofabstraction.
