Researchers have developed a new framework called ARCHIVE for more accurate and efficient ambiguity detection in open-domain question answering systems. Unlike previous methods that conflate answer diversity with ambiguity, ARCHIVE identifies ambiguity through logical conflict, determining if valid answers can coexist under a single interpretation. This approach combines a fast encoder for simple cases with a reasoning module for complex logical relations, and it is validated on a new benchmark called QuireQA. ARCHIVE demonstrates significant improvements in accuracy and speed compared to existing methods. AI
