Three state-of-the-art statistical parsers are com- bined to produce more accurate parses, as well as new bounds on achievable Treebank parsing accu- racy. Two general approaches are presented and two combination techniques are described for each ap- proach. Both parametric and non-parametric mod- els are explored, i The resulting parsers surpass the best previously published performance results for the Penn Treebank.
