TuLiPA

Abstract

In this paper, we present an open-source parsing environment (Tübingen Linguistic Parsing Architecture, TuLiPA) which uses Range Concatenation Grammar (RCG) as a pivot formalism, thus opening the way to the parsing of several mildly context-sensitive formalisms. This environment currently supports tree-based grammars (namely Tree-Adjoining Grammars (TAG) and Multi-Component TreeAdjoining Grammars with Tree Tuples (TT-MCTAG)) and allows computation not only of syntactic structures, but also of the corresponding semantic representations. It is used for the development of a tree-based grammar for German.

A statistical model for grammar mapping

“…The elementary trees of these LTAGs are annotated with feature structures which serve to make them independent of a certain textual domain, as opposed to extracted grammars, which depend on the textual domain of the data from which they have been extracted. The English XTAG grammar (XTAG-Group 2001), the Korean XTAG grammar (Han et al 2002), the TAG-based grammar for German (Kallmeyer et al 2008), and the French LTAG (Abeillé, Clément and Toussenel 2003) are some examples of manually crafted LTAGs.…”
