Conversion between different grammar frameworks is of great importance to comparative performance analysis of the parsers developed on them. This tool can convert CCG derivations to PTB trees by using Max Entropy models as well as visualizing the tree graphs. The main technical innovation presented here is the effective conversion method which achieves a F score over 95%.
- Visualize PTB trees.
- Visualize CCG derivations and the converted PTB result according to different POS tags used.
- Convert CCG derivations to PTB trees and evaluate the converted results using EVALB.
Great tool to show tree converter
