Mixing and blending syntactic and semantic dependencies

Samuelsson, Yvonne and Täckström, Oscar and Velupillai, Sumithra and Eklund, Johan and Fishel, Mark and Saers, Markus (2008) Mixing and blending syntactic and semantic dependencies. In: CoNLL 2008: Proceedings of the Twelfth Conference on Computational Natural Language Learning, August 2008, Manchester, England.



Our system for the CoNLL 2008 shared task uses a set of individual parsers, a set of stand-alone semantic role labellers, and a joint system for parsing and semantic role labelling, all blended together. The system achieved a macro averaged labelled F1- score of 79.79 (WSJ 80.92, Brown 70.49) for the overall task. The labelled attachment score for syntactic dependencies was 86.63 (WSJ 87.36, Brown 80.77) and the labelled F1-score for semantic dependencies was 72.94 (WSJ 74.47, Brown 60.18).
