This afternoon, Wednesday 28/9, at 4pm in room A1.04, we will have:
Andreas van Cranenburgh (MoL) on:
Discontinuous Data-Oriented Parsing: A mildly context-sensitive
all-fragments grammar
Recent advances in parsing technology have made treebank parsing with
discontinuous constituents possible, with parser output of competitive
quality (Kallmeyer and Maier, 2010). We apply Data-Oriented Parsing
(DOP) to a grammar formalism that allows for discontinuous trees
(LCFRS). Decisions during parsing are conditioned on all possible
fragments, resulting in improved performance. Despite the fact that both
DOP and discontinuity present formidable challenges in terms of
computational complexity, the model is reasonably efficient, and
surpasses the state of the art in discontinuous parsing (based on a
joint paper with Remko Scha and Federico Sangati).
