CoNLL-X Shared Task on Multilingual Dependency Parsing
Sabine Buchholz,Erwin Marsi +1 more
TL;DR: How treebanks for 13 languages were converted into the same dependency format and how parsing performance was measured is described and general conclusions about multi-lingual parsing are drawn.
Journal ArticleDOI
MaltParser: A language-independent system for data-driven dependency parsing
Joakim Nivre,Johan Hall,Jens Nilsson,Atanas Chanev,Gülşen Eryiğit,Sandra Kübler,Svetoslav Marinov,Erwin Marsi +7 more
TL;DR: Experimental evaluation confirms that MaltParser can achieve robust, efficient and accurate parsing for a wide range of languages without language-specific enhancements and with rather limited amounts of training data.
Proceedings Article
Explorations in Sentence Fusion
Erwin Marsi,Emiel Krahmer +1 more
TL;DR: This paper proposed a generalized version of alignment which not only indicates which words and phrases should be aligned, but also labels these in terms of a small set of primitive semantic relations, indicating how words from the two input sentences relate to each other.
Journal ArticleDOI
Care episode retrieval: distributional semantic models for information retrieval in the clinical domain.
Hans Moen,Hans Moen,Hans Moen,Filip Ginter,Erwin Marsi,Laura-Maria Peltonen,Laura-Maria Peltonen,Tapio Salakoski,Tapio Salakoski,Sanna Salanterä,Sanna Salanterä +10 more
TL;DR: Several methods for information retrieval, focusing on care episode retrieval, based on textual similarity, are presented, which suggest that several of the methods proposed outperform a state-of-the art search engine (Lucene) on the retrieval task.
Proceedings ArticleDOI
Classification of Semantic Relations by Humans and Machines
Erwin Marsi,Emiel Krahmer +1 more
TL;DR: This paper investigates the performance of human annotators on the task of manually aligning dependency analyses of the respective sentences and of assigning one of five semantic relations to the aligned phrases and describes and evaluates a combined alignment and classification algorithm.
