Joint arc-factored parsing of syntactic and semantic dependencies
(2013-05)
Article
Restricted access - publisher's policyIn this paper we introduce a joint arc-factored model for syntactic and semantic dependency parsing. The semantic role labeler predicts the full syntactic paths that connect predicates with their arguments. This process ... -

Projective dependency parsing with perceptron
(2010)
Conference report
Open AccessWe describe an online learning dependency parser for the CoNLL-X Shared Task, based on the bottom-up projective algorithm of Eisner (2000). We experiment with a large feature set that models: the tokens involved in ... -
Real-life translation quality estimation for MT system selection
(2013)
Conference lecture
Open AccessResearch on translation quality annotation and estimation usually makes use of standard language, sometimes related to a specific language genre or domain. However, real-life machine translation (MT), performed for instance ... -
Robust Estimation of Feature Weights in Statistical Machine Translation
(2010)
Conference lecture
Open AccessWeights of the various components in a standard Statistical Machine Translation model are usually estimated via Minimum Error Rate Training. With this, one finds their optimum value on a development set with the ... -
