Cross-Lingual Projection of LFG F-Structures: Building an F-Structure Bank for Polish

Various methods aim at overcoming the shortage of NLP resources, especially for resource-poor languages. We present a cross-lingual projection account that aims at inducing an annotated treebank to be used for parser induction for Polish. Our approach builds on Hwa et al.’s projection method [7] that we adapt to the LFG framework. The goal of the experiment is the induction of an LFG f-structure bank for Polish. The projection yields competitive results. The resulting f-structure bank may be used to train a dependency parser for Polish, or for automatic induction of a probabilistic LFG grammar.
