Table 8:

Pairwise model agreement scores for phrase-structure parsing, as measured by average exact match on trees from the validation set of the PTB for which some pair of models produced different trees. Self-agreement (diagonals) are 100%. Exact match is symmetric; hence the table is also symmetric.
