International Workshop on Semantic Evaluations
                      an ACL-SIGLEX event

                    Second Call for Participation
                  (Please note the date changes)


The purpose of the SensEval/SemEval workshops
( is to evaluate semantic
analysis systems. SemEval-2012 is the next event in the series.

The first three workshops, SensEval-1 through SensEval-3, were focused
on word sense disambiguation, each time growing in the number of
languages offered in the tasks and in the number of participating
teams. In 2007 the workshop was renamed SemEval and the next two
workshops SemEval-2007 and SemEval-2010 the nature of the tasks
evolved to include semantic analysis tasks outside of word sense

We are now ready for SemEval-2012!  SemEval-2012 is associated with the
new *SEM, First Joint Conference on Lexical and Computational Semantics,
and co-located with NAACL, Montreal, Canada, June 7-8, 2012.

The list of tasks with complete descriptions and task related data and scripts
is now available.  As with previous evaluations, participants are provided with
specific training data, and will have the chance to test their systems
on common data sets.  Here is a short preview of the tasks that are offered
(for more details, please visit our webpage):

1. English Lexical Simplification
2. Measuring Degrees of Relational Similarity
3. Spatial Role Labeling
4. Evaluating Chinese Word Similarity
5. Chinese Semantic Dependency Parsing
6. Semantic Textual Similarity
7. COPA: Choice Of Plausible Alternatives
8. Cross-lingual Textual Entailment for Content Synchronization

Important dates:

March 15, 2012   Start of evaluation period (test data available)
April 1, 2012  End of evaluation period (results due)
April 16, 2012 Paper submission deadline [EXTENDED]
