コーパス言語学概論・演習

the current "state of the art" for parsing is pretty much dominated by PCFG-based parsers, for example Charniak and Johnson's reranking parser, which uses a lexicalized PCFG with markovization: http://citeseer.ist.psu.edu/charniak05coarsetofine.html

or Klein and Pertrov's parser which automatically finds refinements of a treebank grammar: http://www.cs.berkeley.edu/~petrov/data/naacl07.pdf (for more references, also have a look at http://aclweb.org/aclwiki/index.php?title=Parsing_%28State_of_the_art%29 )

For dependency parsing, you could have a look at what the participants of the CoNLL 2007 shared task used: http://nextens.uvt.nl/depparse-wiki/SharedTaskWebsite (you can get the respective papers on the ACL anthology page at http://www.aclweb.org/anthology-new/signll.html#2007-0 ).
