The FACT shared task is part of IberLEF 2019 and is organized by Grupo PLN-InCo (UdelaR - Uruguay), Grupo de Procesamiento del Lenguaje Natural (FaMAF, UNC, Argentina), and GRIAL (UB-UAB-UDL, España).

Task description:
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.

Factuality is understood, following Sauri (2008), as the category that determines the factual status of events, that is, whether events are presented or not as certain. The goal of this task is the determination of the status of verb events with respect to factuality in Spanish texts. In this task facts are not verified in regard to the real world, just assessed with respect to how they are presented by the source (in this case the writer), that is, the commitment of the source to the truth-value of the event. In this sense, the task could be conceived as a core procedure for other tasks such as fact-checking and fake-news, making it possible, in future tasks, to compare what is narrated in the text (fact tagging) to what is happening in the world (fact-checking and fake-news).

For this task, we established three possible categories:

Facts: current and past situations in the world that are presented as real.
Counterfacts: current and past situations that the writer presents as not having happened.
Undefined: possibilities, future situations, predictions, hypothesis and other options. Situations presented as uncertain since the writer does not commit openly to the truth-value either because they have not happened yet or because the author does not know.

The objective of this task is to automatically propose a factual tag for each event in the text.
