Temporal Relation Extraction: the Event Ordering Task

Although most Natural Language Processing tasks, such as Text Classification and Natural Language Translation, have experienced a major performance improvement due to recent advances in neural network architectures, Temporal Relation Extraction remains an open challenge. This leaves the door open for new research questions. In this paper, we provide a brief summary of the task and some of the recent efforts that have been made to solve it. In addition, some research opportunities yet to be explored are also discussed.
