The system uses Java in general, Prolog for lexical entries and custom domain-specific languages based on Functional Grammar and Functional Discourse Grammar notation, implemented using the ANTLR parser generator. We show how linguistic and technological parts can be brought together in a natural language processing system and how domain-specific languages can be used as a tool for consistent formal notation in linguistic description.12 pages, 9 figures; based on work presented at the 12th International Conference on Functional GrammarComputation and LanguageI.2.4; I.2.7text
