+In this paper we present the second edition of the FACT shared task (Factuality Annotation and Classification
+Task), included in IberLEF2020. The main objective of this task is to advance in the study of the factuality of
+the events mentioned in texts. This year, the FACT task includes a subtask on event identification in addition
+to the factuality classification subtask. We describe the submitted systems as well as the corpus used, which is
+the same used in FACT 2019 but extended by adding annotations for nominal events.
