International Workshop on Semantic Evaluation

What is SemEval?

SemEval is a series of international natural language processing (NLP) research workshops whose mission is to advance the current state of the art in semantic analysis and to help create high-quality annotated datasets in a range of increasingly challenging problems in natural language semantics. Each year's workshop features a collection of shared tasks in which computational semantic analysis systems designed by different teams are presented and compared.

SemEval is sponsored by the SIGLEX Special Interest Group on the Lexicon of the Association for Computational Linguistics. For more information on SemEval and its history, please see


The 14th edition of SemEval features 12 tasks on topics ranging from lexical semantic change to offensive language in social media.

It will take place December 12–13, 2020 in Barcelona, Spain online, colocated with COLING 2020.




The 15th edition of SemEval will feature tasks ranging from prediction of lexical complexity to learning with disagreements, and including several cross-lingual and multi-modal tasks.

The evaluation period will take place in January 2021. See the SemEval-2021 homepage for details.

The workshop will take place August 5–6, 2021 in Bangkok, Thailand, colocated with ACL-IJCNLP 2021.


The call for task proposals is open!
