CoNLL-X-code

From Dyna

In this paper (reference below) we described the performance of a dependency parsing system written partly in Dyna. The algorithms used in that paper are given in Dyna here; the C++ code that the current Dyna compiler produces is here.

This parser and labeler formed part of our entry in the 2006 CoNLL shared task. It didn't perform very competitively, largely because it was designed for speed and precision of dependency links (not recall). These Dyna programs might be helpful examples, nonetheless.
