Researchers have investigated methods for evaluating retrieval quality when the total number of relevant documents is unknown, a common scenario in real-world applications with large, dynamic knowledge bases. The study correlates standard retrieval quality metrics with judgments made by large language models (LLMs) on response quality derived from retrieved documents. Experiments were conducted on datasets with a limited number of relevant documents, and a new, simpler retrieval quality measure was proposed that does not require prior knowledge of the total relevant document count.
