... has opened up the pos- sibility of grammar induction through par- tial transfer across bitext. We consider generative and discriminative models for dependency grammar induction that use word-level ... Hwa et al. (2005) explore transfer of deeper syntactic structure: dependency grammars. Dependency and con- stituency grammar formalisms have long coex- isted and competed in linguistics, e...

... ducing grammars from sparsely labeled training data (e.g., only higher-level constituent labels), we propose an adaptation strategy, which pro- duces grammars that parse almost as well as grammars ... a directly in- duced grammar parses test sentences with 66% accuracy, whereas an adapted grammar parses with 91% accuracy, which is only 2% lower than the score of a grammar ind...
