In this paper, we show an approach to ex-
tracting different types of constraint rules
from a dependency treebank. Also, we
show an approach to integrating these con-
straint rules into a dependency data-driven
parser, where these constraint rules in-
form parsing decisions in specific situa-
tions where a set of parsing rule (which is
induced from a classifier) may recommend
several recommendations to the parser.
Our experiments have shown that parsing
accuracy could be improved by using dif-
ferent sets of constraint rules in combina-
tion with a set of parsing rules. Our parser
is based on the arc-standard algorithm of
MaltParser but with a number of exten-
sions, which we will discuss in some de-
