Abstract: Several researchers have considered the use of passages within documents as useful units of representation as individual passages may capture accurately the topic of discourse in a document. In this work, each document is indexed as a series of unique passages. We explore and analyse a number of similarity measures which take into account the similarity at passage level with the aim of improving the quality of the answer set. We define a number of such passage level approaches and compare their performance. Mean average precision (MAP) and precision at k documents (P@k) are used as measures of the quality of the approaches. The results show that for the different test collections, the rank of a passage is a useful measure, and when used separately or in conjunction with the document score can give better results as compared to other passage or document level similarity approaches.
