Incremental Monoidal Grammars

2 Jan 2020  ·  Dan Shiebler, Alexis Toumi, Mehrnoosh Sadrzadeh ·

In this work we define formal grammars in terms of free monoidal categories, along with a functor from the category of formal grammars to the category of automata. Generalising from the Booleans to arbitrary semirings, we extend our construction to weighted formal grammars and weighted automata. This allows us to link the categorical viewpoint on natural language to the standard machine learning notion of probabilistic language model.
