... be performed when parsing an input string, something that is not offered by CFGs. In other words, PDAs can be associated to parsing strategies for context- free languages. More precisely, parsing strategies are ... left-corner parsing strategy can be extended probabilistically, and later by (Abney et al., 1999) who show that the pure top-down parsing strategy and a specific type of s...

... Introduction Treebank-based probabilistic parsing has been the subject of intensive research over the past few years, resulting in parsing models that achieve both broad coverage and high parsing accuracy (e.g., ... UK keller@inf.ed.ac.uk Abstract We present a probabilistic parsing model for German trained on the Negra tree- bank. We observe that existing lexicalized parsing models...

There are D document sets, M documents in each set, N M words in document M, and C syntax classes. proach would be to model the syntax and semantic words used in a document collection ... assuming that each document is generated solely from one topic distribution that is shared throughout each document set. This results in a smoothed language model for each document set’s content ......

It is thought that more effective, high-performance spoken monologue parsing could be achieved ... shortened and the parsing accuracy can be increased.
