LTG Systems Best Performers at 2012 *SEM Shared Task
Two teams from the Oslo Language Technology Group (LTG) participated highly successfully in the 2012 Shared Task on Resolving the Scope and Focus of Negation of the First Joint Conference on Lexical and Computational Semantics (*SEM). Among nine competing teams from all over the world, LTG systems hold the first, second, and third ranks in the closed track, and the first rank in the open track.
This work continues the tradition of strong results on the detection and resolution of speculation and negation, which had given rise to the overall best performer in the 2010 CoNLL Shared Task and a Best Paper Award at the 2011 LBM. We are particularly happy for Emanuele Lapponi, MSc student in our study programme in Informatics: Language and Communication, whose submission reflects the results of his thesis work and ranked third in the closed and first in the open track, respectively.
