LG AI Research proposes PromptRank, a data-efficient retrieval method for multi-hop question answering that uses a large language model to rerank document paths based on the conditional likelihood of generating the question given the path.

Enters our approach, dubbed PromptRank. ... PromptRank consists of two steps. First, a simple unsupervised retrieval method picks an initial set of document paths that have the potential to be relevant to the given question. Second, a more complex reranker model reweighs (or reranks) the paths obtained in the first step based on their relevance to the question.
