While the average performance of statisti- cal parsers gradually improves, they still at- tach to many sentences annotations of rather low quality. The number of such sentences grows when the …...

In this paper, we consider classifying word positions by whether or not they can either start or end multi-word constituents. This provides a mechanism for “closing” chart cells during context-free …...

Efficient decoding for syntactic parsing has become a necessary research area as statisti- cal grammars grow in accuracy and size and as more NLP applications leverage syntac- tic analyses. We …...

AbstractPrepositional phrase (PP) attachment disambiguation is a known challenge in syntactic parsing. The lexical sparsity associated with PP attachments motivates research in word representations that can capture pertinent syntactic and …...
