In the training phase, each individual SSVM is tra...

... a pattern with which to expand it and then filling out that pattern with words drawn from a unigram distribution. This kind of coupled generative process can be naturally formalized with tree ... the rich literature on tree automata. This paper makes the connection concrete with a tree transducer based semantic parsing model and suggests that other models can be interpreted in a simi...

Secondly, the functor A no or B gets an argument B or A no respectively and makes a noun phrase A no B w...

Increasing the beam size beyond this value did not significantly effect parsing accuracy. For ... need- ing to have data labeled with those features in ad- vance. Instead, a labeling with these features can be induced as part of the training process. The difficulty with...
