SwiRL is a Semantic Role Labeling (SRL) system for English constructed on top of the full syntactic analysis of text. Achieved state-of-the-art performance in the CoNLL 2005 SRL evaluation.
Charniak Parser (included), Xavi Carreras' AdaBoost library (included).
It has state-of-the-art performance: currently its F1 on the WSJ corpus is 77+, and on the Brown corpus it is 66+ points. SwiRL ranks fifth among the systems that participated at the CoNLL 2005 shared task evaluation, but all the systems that scored higher were actually combinations of several individual models.
