Peng QI      

I'm currently a postdoctoral research fellow in the Centre for Trusted Internet and Community, National University of Singapore, under the supervision of Prof. Wynne Hsu and Prof. Mong Li Lee. I received my Ph.D. degree at this June in the Institute of Computing Technology, Chinese Academy of Sciences, supervised by Prof. Juan Cao. I also had a one-year visiting study in NExT++, NUS, supervised by Prof. Tat-Seng Chua.

My research interests mainly lie in combating misinformation, multimedia content analysis, and social media mining.

This paper is the first comprehensive survey targeted at combating online misinformation videos.

Two Heads Are Better Than One: Improving Fake News Video Detection by Correlating with Neighbors
Peng Qi, Yuyang Zhao, Yufeng Shen, Wei Ji, Juan Cao, Tat-Seng Chua
ACL Findings, 2023     PDF

This paper proposes a model-agnostic cross-sample framework NEED for detecting fake news videos, which utilizes the neighbor relationship between the related news videos in the same event and thus can largely improve the performance of existing single-sample detectors. This paper is a successful attempt to combine automatic fake news detection and fact-checking, and firstly proves the effectiveness of debunking videos in detection.

FakeSV: A Multimodal Benchmark with Rich Social Context for Fake News Detection on Short Video Platforms
Peng Qi, Yuyan Bu, Juan Cao, Wei Ji, Ruihao Shui, Junbin Xiao, Danding Wang, Tat-Seng Chua
AAAI, 2023     PDF / Code

We construct the largest Chinese fake news short video dataset, namely FakeSV. This dataset contains complete news contents and rich social context under different events, and thus can support a wide range of research tasks related to fake news. It firstly provides abundant debunking videos accompanying the fake and real news videos. We provide exploratory multi-perspective data analysis, which reveals some interesting and insightful phenomenons. Moreover, we design a new multimodal detection model as the SOTA method in this benchmark. We also re-implement 11 single-modal and 4 multimodal methods as baseline methods.

Improving Fake News Detection by Using an Entity-enhanced Framework to Fuse Diverse Multimodal Clues

MM, 2021     PDF

This paper explores three valuable text-image correlations in multimodal fake news: entity inconsistency, mutual enhancement and text complementation. For better multimodal reasoning, this paper firstly import the visual news entities into multimodal fake news detection, which helps to understand the news-related high-level semantics of images and bridge the high-level semantic correlations of news text and images.

Exploring the Role of Visual Content in Fake News Detection
Juan Cao, Peng Qi, Qiang Sheng, Tianyun Yang, Junbo Guo, Jintao Li
Disinformation, Misinformation, and Fake News in Social Media: Emerging Research Challenges and Opportunities (Book), 2020     PDF

This chapter presents a comprehensive review of the visual content in fake news, including the basic concepts, effective visual features, representative detection methods and challenging issues of multimedia fake news detection.

Exploiting Multi-domain Visual Information for Fake News Detection
Peng Qi, Juan Cao, Tianyun Yang, Junbo Guo, Jintao Li
ICDM, 2019     PDF     Citation: 150+

This paper firstly analyze the images in fake news from both the physical and semantic levels, and thus propose a two-stream neural network which fuses the frequency and pixel domains information.
