Try the EP4IR (English Prases for IR) parser from
It is quite fast, runs under Windows and Unix/Linux. The present
version 2.5 produces Head/Modifier trees, a special form of
dependency trees.

Both the AGFL system and the EP4IR parser are under GPL. A new
version (produces richer dependency relations, more coverage,
better precision and recall, even faster) is nearing distribution.
If you are interested to use a beta version 2.6, contact me.
