CoverageBench: Evaluating Information Coverage across Tasks and Domains

ArXi:2603.20034v1 Announce Type: cross We wish to measure the information coverage of an ad hoc retrieval algorithm, that is, how much of the range of available relevant information is covered by the search results. Information coverage is a central aspect for retrieval, especially when the retrieval system is integrated with generative models in a retrieval-augmented generation (RAG) system. The classic metrics for ad hoc retrieval, precision and recall, reward a system as and relevant documents are retrieved.
