DEFAME: Dynamic Evidence-based FAct-checking with Multimodal Experts
DEFAME is a dynamic evidence-based fact-checking system that uses multimodal experts to verify claims across text and images. It operates in six stages, planning actions, executing tools like web search or image search, summarizing results, developing the fact-check argument, predicting a verdict, and justifying the final answer. This end-to-end framework dynamically selects evidence retrieval methods for open-domain verification.
