Hi Niels,

Sketch Engine (http://sketchengine.co.uk) now supports querying dependency trees represented in CONLL format (Malt parser output is in CONLL format). Word sketches (profiles) and thesaurus can also be extracted from the parsed data.

Paper related to handling CONLL format in Sketch Engine: http://www.lrec-conf.org/proceedings/lrec2012/pdf/585_Paper.pdf

I have uploaded a portion of Penn Treebank (dependency) with which you can play with at http://corpdev.sketchengine.co.uk/run.cgi/first_form?corpname=23399c07

Sample CQL (corpus query language) queries:

1. All examples of dependency relation OBJ: [deprel="OBJ"]<http://bit.ly/Q2Pv6F>

2. All Keywords in Context of dependency relation OBJ: 1:[] []{0,5} 2:[deprel="OBJ"] & 2.head=1.id <http://bit.ly/QEWGIR>

3. Tag patterns of OBJ relation: 1:[] []{0,5} 2:[deprel="OBJ"] & 2.head=1.id<http://bit.ly/QEWZTO>

4. Word Sketch of a word, e.g. give-v, extracted from dependency corpus: http://bit.ly/QEXptr

For more details, please contact personally.
