The retrieval scoring function of Dirichlet-prior smoothing is written by. -H. Na et al. From Eq. (6), Score(Q,D1) > Score(Q,D2). Thus, Dirichlet-prior smoothing belongs to a length-normalized scoring function. Similarly, we can show that Jelinek-Mercer □ smoothing is also length-normalized one. 1 Experimental Setting For evaluation, we used six TREC test collections. Table 1 summarizes the basic information of each test collection. TREC4-AP is the sub-collection of Associated Press in disk 1 and disk 2 for TREC4.

SPCOMPLETE(D): It consists of all possible subsequent words in document D, and equivalently denoted as SPVAR(1,…|D|)(D), where |D| is the length of document. It is a special type of arbitrary passage. Although completely-arbitrary passage is conceptually simple, the number of possible passages in D is 2|D|-1, which is an exponentially increasing function of the length of document. Therefore, it may be intractable to perform the passage retrieval based on completely-arbitrary passages, since we cannot pre-index all possible arbitrary passages, and cannot compare the scores of all possible passages at retrieval time.
