XFake: Explainable Fake News Detector with Visualizations
This demo paper presents an incremental tool for end-users to identify news credibility with visualizations, but lacks concrete performance numbers.
The authors tackled the problem of fake news detection by developing XFake, an explainable system that jointly analyzes attributes and statements, and demonstrated it on a real-world PolitiFact dataset with thousands of verified political news items.
In this demo paper, we present the XFake system, an explainable fake news detector that assists end-users to identify news credibility. To effectively detect and interpret the fakeness of news items, we jointly consider both attributes (e.g., speaker) and statements. Specifically, MIMIC, ATTN and PERT frameworks are designed, where MIMIC is built for attribute analysis, ATTN is for statement semantic analysis and PERT is for statement linguistic analysis. Beyond the explanations extracted from the designed frameworks, relevant supporting examples as well as visualization are further provided to facilitate the interpretation. Our implemented system is demonstrated on a real-world dataset crawled from PolitiFact, where thousands of verified political news have been collected.
