ACGtk

Abstract Categorial Grammar Development Toolkit

Keywords: Natural language processing - NLP - Syntactic analysis - Semantics

Scientific Description: Abstract Categorial Grammars (ACG) are a grammatical formalism in which grammars are based on typed lambda-calculus. A grammar generates two languages: the abstract language (the language of parse structures), and the object language (the language of the surface forms, e.g., strings, or higher-order logical formulas), which is the realization of the abstract language.

ACGtk provides two software tools to develop and to use ACGs: acgc, which is a grammar compiler, and acg, which is an interpreter of a command language that allows one, in particular, to parse and realize terms.

Functional Description: ACGtk provides softwares for developing and using Abstract Categorial Grammars (ACG).

Release Functional Description: This version removes the dependency to obsolete packages. It also provides a better handling of the command line interface.

News Of The Year: The new version removes dependencies to obsolete libraries. It improves the command line interface and prepares the integration of new functionalities and optimizations.
