International Workshop on Semantic Evaluations
an ACL-SIGLEX event
Second Call for Participation

SemEval 2013, the 7th International Workshop on Semantic Evaluations invites participation in a broad
range of tasks in the semantic analysis of natural language. The aim of the SemEval series of workshops
is to extend 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. For more
information on SemEval, please see

Participants will be able to choose from a wide range of tasks in semantic analysis covering temporal
expressions, spatial expressions, sentiment analysis, semantic similarity, textual entailment,
bioinformatics, word sense disambiguation, and word sense induction amongst others. Participants will
be provided with training data sets well in advance to help them develop their systems.

SemEval-2013 is associated with the *SEM (Joint Conference on Lexical and Computational Semantics) to be
co-located with the North American Chapter of the Association for Computational Linguistics and Human
Language Technologies 2013 conference (NAACL HLT), which will take place in Atlanta, USA, the week of
June 9-14. The list of tasks with complete descriptions and task related data and scripts are now available
from the SemEval-2012 website at Here is a short preview of the
tasks that are being offered:

1. TempEval-3 Temporal Annotation
2. Sentiment Analysis in Twitter
3. Spatial Role Labeling
4. Free Paraphrases of Noun Compounds
5. Evaluating Phrasal Semantics
