In: 12th Conference on Computational Natural Language Learning, 16-17 Aug 2008, Manchester, UK.


In this paper we describe the system submitted to the closed challenge of the CoNLL-2008 shared task on joint parsing of syntactic and semantic dependencies. The system that we present extracts syntactic and semantic dependencies independently. Syntactic dependencies are processed with the MaltParser 0.4. Semantic dependencies are processed with a combination of memory-based classifiers. We focus on the memory-based semantic role labeler, which achieves 71,88 labeled F1.
