From the initial 4,683,777 nodes (of sections 02-21), the heuristic removed 1,503,100 nodes with a loss of 2.6% of the total arguments.
for accomplishing the CoNLL 2005 Shared Task on Semantic Role Labeling (Carreras and Màrquez, 2005), we capitalized on our experience on the semantic shallow parsing by extending our system, widely experimented on PropBank and frameNet (Giuglea and Moschitti, 2004) data, with a twostep boundary detection and a hierarchical argument classification strategy.
