A joint model for parsing syntactic and semantic dependencies Lluis Martorell, Xavier; Màrquez Villodre, Lluís (Coling 2008 Organizing Committee, 2008)
Open AccessThis paper describes a system that jointly parses syntactic and semantic dependencies, presented at the CoNLL-2008 shared task (Surdeanu et al., 2008). It combines online Peceptron learning (Collins, 2002) with a parsing ...
A second-order joint Eisner model for syntactic and semantic dependency parsing Lluis Martorell, Xavier; Bott, Stefan Markus; Màrquez Villodre, Lluís (2009)
Restricted access - publisher's policyWe present a system developed for the CoNLL-2009 Shared Task (Hajic et al., 2009). We extend the Carreras (2007) parser to jointly annotate syntactic and semantic dependencies. This state-of-the-art parser factorizes the ...
A shortest-path method for arc-factored semantic role labeling Lluis Martorell, Xavier; Carreras Pérez, Xavier; Márquez Villodre, Luís (2014)
Restricted access - publisher's policyWe introduce a Semantic Role Labeling (SRL) parser that finds semantic roles for a predicate together with the syntactic paths linking predicates and arguments. Our main contribution is to formulate SRL in terms of ...
Joint arc-factored parsing of syntactic and semantic dependencies Lluis Martorell, Xavier; Carreras Pérez, Xavier; Màrquez Villodre, Lluís (2013-05)
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 ...
