Overview of the TAC2013 Knowledge Base Population Evaluation: English Slot Filling and Temporal Slot Filling.
Mihai Surdeanu · 2013
We overview two tracks of the TAC2013 Knowledge Base Population (KBP) evaluation: English slot filling (SF) and temporal slot filling (TSF). The goal of these two KBP tracks is to promote research in the extraction of relations between named entities from free text (SF), and identify the temporal intervals when these relations were valid (TSF). The main changes this year include the requirement for a stricter textual justification of the extracted relations for SF, and a simplification of the TSF task, where the relation to be temporally grounded is given as input. These two tracks attracted 43 registered teams, out of which 20 teams submitted a run in at least one of the tracks.
