Temporal relation extraction systems aim to identify and classify the temporal relation between a pair of entities provided in a text. For instance, in the sentence "Bob sent a message to Alice while she was leaving her birthday party." one can infer that the actions "sent" and "leaving" entails a temporal relation that can be described as "simultaneous".

The TempEval-3 task is described, incorporating a three-part task structure covering event, temporal expression and temporal relation extraction; a larger dataset; and single overall task quality scores.
CATENA, a sieve-based system to perform temporal and causal relation extraction and classification from English texts, exploiting the interaction between the temporal and the causal model is presented.
This study employs a structured perceptron together with integer linear programming constraints for document-level inference during training and prediction to exploit relational properties of temporality, together with global learning of the relations at the document level.
It is demonstrated that a pre-trained Transformer model is able to transfer from the weakly labeled examples to human-annotated benchmarks in both zero-shot and few-shot settings, and that the masking scheme is important in improving generalization.
This work extends the classification model’s task loss with an unsupervised auxiliary loss on the word-embedding level of the model to ensure that the learned word representations contain both task-specific features and more general features learned from the unsuper supervised loss component.
A novel method, Clinical Temporal ReLation Exaction with Probabilistic Soft Logic Regularization and Global Inference (CTRL-PG) to tackle the problem at the document level, and significantly outperforms baseline methods for temporal relation extraction.
EventPlus as the first comprehensive temporal event understanding pipeline provides a convenient tool for users to quickly obtain annotations about events and their temporal information for any user-provided document.
This work proposes a framework that enhances deep neural network with distributional constraints constructed by probabilistic domain knowledge and solves the constrained inference problem via Lagrangian Relaxation and applies it on end-to-end event temporal relation extraction tasks.
Experimental results on three high-quality event temporal relation datasets demonstrate that incorporated with pre-trained contextualized embeddings, the proposed model achieves significantly better performances than the state-of-the-art methods on all three datasets.
Adding a benchmark result helps the community track progress.
