Towards Explainable Harmful Meme Detection through Multimodal Debate between Large Language Models

1 code implementation24 Jan 2024 Hongzhan Lin, Ziyang Luo, Wei Gao, Jing Ma, Bo wang, Ruichao Yang

Then we propose to fine-tune a small language model as the debate judge for harmfulness inference, to facilitate multimodal fusion between the harmfulness rationales and the intrinsic multimodal information within memes.

GOAT-Bench: Safety Insights to Large Multimodal Models through Meme-Based Social Abuse

no code implementations3 Jan 2024 Hongzhan Lin, Ziyang Luo, Bo wang, Ruichao Yang, Jing Ma

The exponential growth of social media has profoundly transformed how information is created, disseminated, and absorbed, exceeding any precedent in the digital age.

Collaborative Synthesis of Patient Records through Multi-Visit Health State Inference

1 code implementation22 Dec 2023 Hongda Sun, Hongzhan Lin, Rui Yan

Furthermore, we propose to generate medical reports to add textual descriptions for each medical event, providing broader applications for synthesized EHR data.

WSDMS: Debunk Fake News via Weakly Supervised Detection of Misinforming Sentences with Contextualized Social Wisdom

1 code implementation25 Oct 2023 Ruichao Yang, Wei Gao, Jing Ma, Hongzhan Lin, Zhiwei Yang

This model only requires bag-level labels for training but is capable of inferring both sentence-level misinformation and article-level veracity, aided by relevant social media conversations that are attentively contextualized with news sentences.

Dual-Scale Interest Extraction Framework with Self-Supervision for Sequential Recommendation

no code implementations16 Oct 2023 Liangliang Chen, Hongzhan Lin, Jinshan Ma, Guang Chen

Nevertheless, the existing approaches just extract each interest independently for the corresponding sub-sequence while ignoring the global correlation of the entire interaction sequence, which may fail to capture the user's inherent preference for the potential interests generalization and unavoidably make the recommended items homogeneous with the historical behaviors.

Zero-Shot Rumor Detection with Propagation Structure via Prompt Learning

1 code implementation2 Dec 2022 Hongzhan Lin, Pengyao Yi, Jing Ma, Haiyun Jiang, Ziyang Luo, Shuming Shi, Ruifang Liu

The spread of rumors along with breaking events seriously hinders the truth in the era of social media.

A Coarse-to-fine Cascaded Evidence-Distillation Neural Network for Explainable Fake News Detection

1 code implementation COLING 2022 Zhiwei Yang, Jing Ma, Hechang Chen, Hongzhan Lin, Ziyang Luo, Yi Chang

Existing fake news detection methods aim to classify a piece of news as true or false and provide veracity explanations, achieving remarkable performances.

A Weakly Supervised Propagation Model for Rumor Verification and Stance Detection with Multiple Instance Learning

no code implementations6 Apr 2022 Ruichao Yang, Jing Ma, Hongzhan Lin, Wei Gao

The diffusion of rumors on microblogs generally follows a propagation tree structure, that provides valuable clues on how an original message is transmitted and responded by users over time.
