TreeGraSP is a research project funded by an ERC Consolidator Grant. The acronym stands for Tree rewriting grammars and the syntax-semantics interface: From grammar development to semantic parsing.
The project is hosted by the University of Düsseldorf and led by Professor Laura Kallmeyer.
TreeGraSP bridges this gap by combining rich linguistic theory with data-driven approaches to large scale statistical grammar induction and to semantic parsing. The novelty of its approach consists in putting semantics at the center of grammar theory, putting an emphasis on multilinguality and typological diversity, and adopting a constructional approach to grammar.
TreeGraSP is interdisciplinary and innovative in serveral respects:
It contributes to the field of linguistics by a) making theories of grammar explicit, b) providing a grammar implementation tool for typologically working linguists and c) developing means to obtain a quantitative grammar theory. And it contributes to the field of computational semantics by providing a probabilistic theory of meaning construal that can be used for textual entailment and reasoning applications.
The challenge lies in the intended transfer between theoretical linguistics and statistical natural language processing.
