A Corpus-based Toy Model for DisCoCat
This work provides a theoretical foundation for computational linguistics by formalizing a mapping in DisCoCat, but it is incremental as it builds on existing paradigms without broad practical applications.
The authors tackled the problem of constructing a concrete mapping from syntax to categorical semantics within the DisCoCat model, resulting in a specific implementation using a toy model of syntax and a category of free R-semimodules.
The categorical compositional distributional (DisCoCat) model of meaning rigorously connects distributional semantics and pregroup grammars, and has found a variety of applications in computational linguistics. From a more abstract standpoint, the DisCoCat paradigm predicates the construction of a mapping from syntax to categorical semantics. In this work we present a concrete construction of one such mapping, from a toy model of syntax for corpora annotated with constituent structure trees, to categorical semantics taking place in a category of free R-semimodules over an involutive commutative semiring R.
