Summary

The authors describe a method that uses discriminative reranking for parsing. It uses the standard Charniak parser to generate the 50 best parse trees for a given sentence. They use the 50 parse trees in a MaxEnt reranker. The results show a small improvement over the state of the art (at the time), but is a significantly more efficient.
