Set-Aligning Framework for Auto-Regressive Event Temporal Graph Generation

1 code implementation1 Apr 2024 Xingwei Tan, Yuxiang Zhou, Gabriele Pergola, Yulan He

Recent studies, which employ pre-trained language models to auto-regressively generate linearised graphs for constructing event temporal graphs, have shown promising results.

Event Temporal Relation Extraction with Bayesian Translational Model

no code implementations10 Feb 2023 Xingwei Tan, Gabriele Pergola, Yulan He

Existing models to extract temporal relations between events lack a principled method to incorporate external knowledge.

Event-Centric Question Answering via Contrastive Learning and Invertible Event Transformation

1 code implementation24 Oct 2022 Junru Lu, Xingwei Tan, Gabriele Pergola, Lin Gui, Yulan He

Our proposed model utilizes an invertible transformation matrix to project semantic vectors of events into a common event embedding space, trained with contrastive learning, and thus naturally inject event semantic knowledge into mainstream QA pipelines.

Extracting Event Temporal Relations via Hyperbolic Geometry

1 code implementation EMNLP 2021 Xingwei Tan, Gabriele Pergola, Yulan He

Recent neural approaches to event temporal relation extraction typically map events to embeddings in the Euclidean space and train a classifier to detect temporal relations between event pairs.
