Ninth Workshop on Syntax, Semantics and Structure in Statistical Translation (SSST-9)

Eneko AGIRRE and Nora ARANBERRI, Ixa Group from University of the Basque Country, together with Dekai Wu, Hong Kong University of Science and Technology (HKUST) and Marine Carpuat, National Research Council (NRC) Canada, are the organizers of the SSST-9 – ”Ninth Workshop on Syntax, Semantics and Structure in Statistical Translation” that takes place in Denver, […]

The Basque WordNet semantic dictionary is a “public resource” now

Machines need computing tools that are more powerful than conventional dictionaries for tasks like information extraction, disambiguation of word meanings, etc. This is in fact the function of the Euskal WordNet application —developed by the IXA Group (UPV/EHU)— which can already be consulted and downloaded free of charge.

This is the first Lexical Knowledge Base […]
