... re-ranking model performs rather well for a limited number of candidate structures, and out- performs Charniak’s model when k = 5. In this case we observe a small boost in performance for the detection ... consistently outper- forms the PCFG model on this metric, as for UAS, and BAS. Concerning the other metrics, as the number of k-best candidates increases, the PCFG model outpe...

Line shows ... memory. For blocks with neutral orientation , we train a separate model that does not use the orientation model feature or the binary features. E.g. for the results in line in Tab...
