VerifAI: A Verifiable Open-Source Search Engine for Biomedical Question Answering

Apr 13, 2026arXiv Information Retrieval

Event Summary

arXiv:2604.08549v1 Announce Type: new Abstract: We introduce VerifAI, an open-source expert system for biomedical question answering that integrates retrieval-augmented generation (RAG) with a novel post-hoc claim verification mechanism. Unlike standard RAG systems, VerifAI ensures factual consisten
