categorial grammar

Categorial grammar is a tradition in formal linguistics which draws inspiration from category theory.

Syntactic “calculus” for categorial grammars was introduced by Lambek formalizing the function type constructors. Derivation trees are encoded by string diagrams.

A seminal article, inspired by the structure of a (non-symmetric) biclosed monoidal category is:

The connection to biclosed monoidal categories is made explicit in:

Pregroup grammar (Wikipedia) is a refinement of this, and categorifies to (non-symmetric) rigid monoidal categories.

Research along similar lines is sometimes described as typelogical grammar:
