Document-Level Event Argument Extraction by Conditional Generation
Sha Li,Heng Ji,Jiawei Han +2 more
- 01 Jun 2021
TL;DR: A document-level neural event argument extraction model is proposed by formulating the task as conditional generation following event templates by creating the first end-to-end zero-shot event extraction framework.
When Do GNNs Work: Understanding and Improving Neighborhood Aggregation
Yiqing Xie,Yiqing Xie,Sha Li,Carl Yang,Raymond Chi-Wing Wong,Jiawei Han +5 more
- 09 Jul 2020
TL;DR: This paper proposes novel metrics that quantitatively measure these two circumstances and integrate them into an Adaptive-layer module and shows that allowing for node-specific aggregation degrees have significant advantage over current GNNs.
Relation Learning on Social Networks with Multi-Modal Graph Edge Variational Autoencoders
Carl Yang,Jieyu Zhang,Haonan Wang,Sha Li,Myungwan Kim,Matthew Walker,Yiou Xiao,Jiawei Han +7 more
- 20 Jan 2020
TL;DR: This work aims to develop a principled and principled frame- work that can pro le user relations as edge semantics in social networks by integrating multi-modal signals in the presence of noisy and incomplete data.
RESIN: A Dockerized Schema-Guided Cross-document Cross-lingual Cross-media Information Extraction and Event Tracking System
Haoyang Wen,Ying Lin,Tuan Lai,Xiaoman Pan,Sha Li,Xudong Lin,Ben Zhou,Manling Li,Haoyu Wang,Hongming Zhang,Xiaodong Yu,Alexander Dong,Zhenhailong Wang,Yi Fung,Piyush Mishra,Qing Lyu,Dídac Surís,Brian Chen,Susan Brown,Martha Palmer,Chris Callison-Burch,Carl Vondrick,Jiawei Han,Dan Roth,Shih-Fu Chang,Heng Ji +25 more
- 01 Jun 2021
TL;DR: This article presented a new information extraction system that can automatically construct temporal event graphs from a collection of news documents from multiple sources, multiple languages (English and Spanish for their experiment), and multiple data modalities (speech, text, image and video).

The Future is not One-dimensional: Complex Event Schema Induction by Graph Modeling for Event Prediction
Manling Li,Sha Li,Zhenhailong Wang,Lifu Huang,Kyunghyun Cho,Heng Ji,Jiawei Han,Clare R. Voss +7 more
- 01 Nov 2021
TL;DR: Temporal Complex Event Schema as discussed by the authors is a graph-based schema representation that encompasses events, arguments, temporal connections and argument relations, and predicts event instances following the temporal complex event schema.
