Multi-Hop Question Answering

A question answering task that requires combining multiple pieces of information to arrive at an answer.

Multi-hop question answering requires the model not merely to match one passage, but to build a chain across multiple pieces of information. The answer may be distributed across different sentences, documents, or sources. This tests retrieval, reasoning, and answer synthesis together. It is especially important in enterprise knowledge assistants and research-oriented systems.
