5 paper cards in Mova's library · 2007–2018

Richard Johansson wrote 5 of the papers Mova reads, in 2007–2018, most of them on Semantic role labeling, Dependency parsing, Treebanks; often with Adam Meyers, Joakim Nivre, Lluís Màrquez.

The profile is the library's match of the name; two people with one name are not always told apart.

Papers

The 2018 Shared Task on Extrinsic Parser Evaluation: On the Downstream Utility of English Universal Dependency Parsers (2018)
The Second Extrinsic Parser Evaluation (EPE 2018) runs the basic UD trees of the English parsers of seventeen participating teams through three downstream systems: biological event extraction (TEES), negation resolution (Sherlock) and opinion analysis.
The CoNLL-2009 Shared Task: Syntactic and Semantic Dependencies in Multiple Languages (2009)
This is the overview of the 2009 CoNLL shared task on joint syntactic dependency parsing and semantic role labelling.
Dependency-based Semantic Role Labeling of PropBank (2008)
The paper builds a PropBank role labeler on top of a dependency parser. A syntactic model (second-order projective, with pseudo-projective handling of non-projective links) and a semantic model (a pipeline of logistic classifiers for sense, argument identification and labeling, followed by a global model) each…
The CoNLL 2008 Shared Task on Joint Parsing of Syntactic and Semantic Dependencies (2008)
The 2008 CoNLL task joined syntactic dependency parsing and semantic role labelling in one dependency formalism.
Extended Constituent-to-Dependency Conversion for English (2007)
The paper argues that the usual head-percolation conversion of the Penn Treebank into dependencies throws away information that the newer Treebank versions contain.
