WP 2 is concerned with syntactic grammar induction. This comprises on the one hand a supervised induction of elementary trees (for TAG/RRG) from treebanks and on the other hand a metagrammar induction starting from an existing TAG/RRG. In contrast to WP 1, WP 2 is concerned with a data-driven probabilistic approach. The resulting probabilistic (meta)grammar can then, in turn, be used for parsing, which requires the implementation of corresponding probabilistic parsers for TAG and RRG.
