Co-training for Commit Classification

1 code implementation WNUT (ACL) 2021 Jian Yi David Lee, Hai Leong Chieu

In this paper, we apply co-training, a semi-supervised learning method, to take advantage of the two views available – the commit message (natural language) and the code changes (programming language) – to improve commit classification.

Coupled Hierarchical Transformer for Stance-Aware Rumor Verification in Social Media Conversations

no code implementations EMNLP 2020 Jianfei Yu, Jing Jiang, Ling Min Serena Khoo, Hai Leong Chieu, Rui Xia

The prevalent use of social media enables rapid spread of rumors on a massive scale, which leads to the emerging need of automatic rumor verification (RV).

Multi-Task Learning Stance Classification

Multi-label and Multi-target Sampling of Machine Annotation for Computational Stance Detection

1 code implementation8 Nov 2023 Zhengyuan Liu, Hai Leong Chieu, Nancy F. Chen

Data collection from manual labeling provides domain-specific and task-aligned supervision for data-driven approaches, and a critical mass of well-annotated resources is required to achieve reasonable performance in natural language processing tasks.

Stance Detection

Guiding Computational Stance Detection with Expanded Stance Triangle Framework

1 code implementation31 May 2023 Zhengyuan Liu, Yong Keong Yap, Hai Leong Chieu, Nancy F. Chen

Stance detection determines whether the author of a piece of text is in favor of, against, or neutral towards a specified target, and can be used to gain valuable insights into social media.

Cross-Topic Rumor Detection using Topic-Mixtures

no code implementations EACL 2021 Xiaoying Ren, Jing Jiang, Ling Min Serena Khoo, Hai Leong Chieu

After deriving a vector representation for each topic, given an instance, we derive a {``}topic mixture{''} vector for the instance based on its topic distribution.

Interpretable Rumor Detection in Microblogs by Attending to User Interactions

1 code implementation29 Jan 2020 Ling Min Serena Khoo, Hai Leong Chieu, Zhong Qian, Jing Jiang

We propose a post-level attention model (PLAN) to model long distance interactions between tweets with the multi-head attention mechanism in a transformer network.

Twitter Homophily: Network Based Prediction of User's Occupation

1 code implementation ACL 2019 Jiaqi Pan, Rishabh Bhardwaj, Wei Lu, Hai Leong Chieu, Xinghao Pan, Ni Yi Puay

In this paper, we investigate the importance of social network information compared to content information in the prediction of a Twitter user{'}s occupational class.

Chemical Structure Elucidation from Mass Spectrometry by Matching Substructures

no code implementations17 Nov 2018 Jing Lim, Joshua Wong, Minn Xuan Wong, Lee Han Eric Tan, Hai Leong Chieu, Davin Choo, Neng Kai Nigel Neo

We take a data driven approach to rank these structures by using neural networks to predict the presence of substructures given the mass spectrum, and matching these substructures to the candidate structures.

Can Syntax Help? Improving an LSTM-based Sentence Compression Model for New Domains

no code implementations ACL 2017 Liangguo Wang, Jing Jiang, Hai Leong Chieu, Chen Hui Ong, D. Song, an, Lejian Liao

In this paper, we study how to improve the domain adaptability of a deletion-based Long Short-Term Memory (LSTM) neural network model for sentence compression.

Universal Dependencies Parsing for Colloquial Singaporean English

1 code implementation ACL 2017 Hongmin Wang, Yue Zhang, GuangYong Leonard Chan, Jie Yang, Hai Leong Chieu

Singlish can be interesting to the ACL community both linguistically as a major creole based on English, and computationally for information extraction and sentiment analysis of regional social media.

Relaxed Survey Propagation for The Weighted Maximum Satisfiability Problem

no code implementations15 Jan 2014 Hai Leong Chieu, Wee Sun Sun Lee

In this paper, we formulate the relaxed survey propagation (RSP) algorithm, which extends the SP algorithm to apply to the weighted Max-SAT problem.
