International Workshop on Semantic Evaluation 2018

SemEval has evolved from the SensEval word sense disambiguation evaluation series. The SemEval wikipedia entry and the ACL SemEval Wiki provide a more detailed historical overview. SemEval-2018 will be the 12th workshop on semantic evaluation and will be collocated with the 16th Annual Conference of the North American Chapter of the Association for Computational Linguistics: Human Language Technologies (NAACL-HLT 2018). SemEval will be held in New Orleans, LA, USA, June 5-6 2018.
