PTVD: A Large-Scale Plot-Oriented Multimodal Dataset Based on Television Dramas
Chen Li, Xutan Peng, Teng Wang +5
Art forms such as movies and television (TV) dramas are reflections of the real world, which have attracted much attention from the multimodal learning community recently. However,…
Dual-Gated Fusion with Prefix-Tuning for Multi-Modal Relation Extraction
Qian Li, Shu Guo, Cheng Ji +3
Multi-Modal Relation Extraction (MMRE) aims at identifying the relation between two entities in texts that contain visual clues. Rich visual content is valuable for the MMRE task,…
On the Security Vulnerabilities of Text-to-SQL Models
Xutan Peng, Yipeng Zhang, Jingfeng Yang +1
Although it has been demonstrated that Natural Language Processing (NLP) algorithms are vulnerable to deliberate attacks, the question of whether such weaknesses can lead to softwa…
On the Latent Holes of VAEs for Text Generation
Ruizhe Li, Xutan Peng, Chenghua Lin
In this paper, we provide the first focused study on the discontinuities (aka. holes) in the latent space of Variational Auto-Encoders (VAEs), a phenomenon which has been shown to…
Generating Disentangled Arguments with Prompts: A Simple Event Extraction Framework that Works
Jinghui Si, Xutan Peng, Chen Li +2
Event Extraction bridges the gap between text and event signals. Based on the assumption of trigger-argument dependency, existing approaches have achieved state-of-the-art performa…
Highly Efficient Knowledge Graph Embedding Learning with Orthogonal Procrustes Analysis
Xutan Peng, Guanyi Chen, Chenghua Lin +1
Knowledge Graph Embeddings (KGEs) have been intensively explored in recent years due to their promise for a wide range of applications. However, existing studies focus on improving…
Cross-Lingual Word Embedding Refinement by Norm Optimisation
Xutan Peng, Chenghua Lin, Mark Stevenson
Cross-Lingual Word Embeddings (CLWEs) encode words from two or more languages in a shared high-dimensional space in which vectors representing words with similar meaning (regardles…
Summarising Historical Text in Modern Languages
Xutan Peng, Yi Zheng, Chenghua Lin +1
We introduce the task of historical text summarisation, where documents in historical forms of a language are summarised in the corresponding modern language. This is a fundamental…
Heuristic Semi-Supervised Learning for Graph Generation Inspired by Electoral College
Chen Li, Xutan Peng, Hao Peng +4
Recently, graph-based algorithms have drawn much attention because of their impressive success in semi-supervised setups. For better model performance, previous studies learn to tr…
Understanding Linearity of Cross-Lingual Word Embedding Mappings
Xutan Peng, Mark Stevenson, Chenghua Lin +1
The technique of Cross-Lingual Word Embedding (CLWE) plays a fundamental role in tackling Natural Language Processing challenges for low-resource languages. Its dominant approaches…
Modeling relation paths for knowledge base completion via joint adversarial training
Chen Li, Xutan Peng, Shanghang Zhang +5
Knowledge Base Completion (KBC), which aims at determining the missing relations between entity pairs, has received increasing attention in recent years. Most existing KBC methods…
A Lightweight Music Texture Transfer System
Xutan Peng, Chen Li, Zhi Cai +3
Deep learning researches on the transformation problems for image and text have raised great attention. However, present methods for music feature transfer using neural networks ar…
