Examples in TACRED cover 41 relation types as used in the TAC KBP challenges (e.g., per:schools_attended and org:members) or are labeled as no_relation if no defined relation is held. These examples are created by combining available human annotations from the TAC KBP challenges and crowdsourcing. Please see our EMNLP paper, or our EMNLP slides for full details. Note: There is currently a label-corrected version of the TACRED dataset, which you should consider using instead of the original version released in 2017. For more details on this new version, see the TACRED Revisited paper published at ACL 2020.
