Grammatriser

Grammatriser is a term used in linguistics and computer science to describe a system or method that transforms grammatical structures. It may refer to a software tool, a theoretical framework, or a combination of both for analyzing, normalizing, or generating grammars in formal or natural languages. A Grammatriser typically operates on formal grammar representations such as context-free grammars, tree-adjoining grammars, feature-based grammars, or abstract syntax trees, and it may employ tree transducers, attribute grammars, or rule-based mapping languages to perform transformations.

In practice, a Grammatriser consists of a grammar repository containing source grammars, a transformation engine that applies a set of transformation rules, and an output layer that yields a target grammar, a parsed-structure representation, or a set of generated sentences. Features can be bidirectional, enabling both the refinement of grammars and the generation of syntactic variants from a single source. The approach is used in fields such as computational linguistics, language technology development, cross-linguistic grammar mapping, grammar induction, and educational tools for illustrating syntactic phenomena.

Common applications include converting constructs between dialects or languages, simplifying grammars for parsers, normalizing data for corpus annotation, paraphrase or style transformation, and helping documentation of endangered languages by producing consistent grammatical representations.

Limitations include potential ambiguity introduced by transformations, the risk of semantic drift if meaning is not carefully constrained, and computational complexity for large grammars. Evaluation typically requires annotated corpora or formal benchmarks.
