“…The line of work most related to ours is on passage-based document retrieval [3,4,7,13,21,24,25,28,30,32,41,44,[53][54][55]. As already noted, the most commonly used passage-based document retrieval methods are ranking a document by the maximum querysimilarity of its passages [4,7,24,25,32,44,55] and by interpolating this similarity with the document-query similarity [4,7,44,55]. We show that our best-performing methods substantially outperform a highly effective method that integrates document-query and passage-query similarities [4].…”
