Locate Then Ask: Interpretable Stepwise Reasoning for Multi-hop Question Answering

1 code implementation COLING 2022 Siyuan Wang, Zhongyu Wei, Zhihao Fan, Qi Zhang, Xuanjing Huang

In this paper, we propose an interpretable stepwise reasoning framework to incorporate both single-hop supporting sentence identification and single-hop question generation at each intermediate step, and utilize the inference of the current hop for the next until reasoning out the final result.

TCIC: Theme Concepts Learning Cross Language and Vision for Image Captioning

no code implementations21 Jun 2021 Zhihao Fan, Zhongyu Wei, Siyuan Wang, Ruize Wang, Zejun Li, Haijun Shan, Xuanjing Huang

Considering that theme concepts can be learned from both images and captions, we propose two settings for their representations learning based on TTN.

An Enhanced Knowledge Injection Model for Commonsense Generation

no code implementations COLING 2020 Zhihao Fan, Yeyun Gong, Zhongyu Wei, Siyuan Wang, Yameng Huang, Jian Jiao, Xuanjing Huang, Nan Duan, Ruofei Zhang

Commonsense generation aims at generating plausible everyday scenario description based on a set of provided concepts.

Bridging by Word: Image Grounded Vocabulary Construction for Visual Captioning

1 code implementation ACL 2019 Zhihao Fan, Zhongyu Wei, Siyuan Wang, Xuanjing Huang

Existing research usually employs the architecture of CNN-RNN that views the generation as a sequential decision-making process and the entire dataset vocabulary is used as decoding space.
