Introduction


 


In order to analyze event references in texts, it is crucial to determine whether they are presented as having taken place or as potential or not accomplished events. This information can be used for different applications like Question Answering, Information Extraction, or Incremental Timeline Construction.


 


Despite its centrality for Natural Language Understanding, this task has been underresearched, with the work by Saurí and Pustejovsky (2009) as a reference for English and Wonsever et al. (2009) for Spanish. The bottleneck to advance on this task has usually been the lack of annotated resources, together with its inherent difficulty. Currently PLN-InCo and GRIAL both have ongoing research projects on this topic, which are producing and will produce such annotated resources. This makes the proposal of this task even more interesting.
