During the last years a great number of Query Performance Prediction methods have been proposed. However, this explosion of prediction method proposals have not been paralleled by ...
Several IR tasks rely, to achieve high efficiency, on a single pervasive data structure called the inverted index. This is a mapping from the terms in a text collection to the docu...
Abstract. In this paper, we extend the SHIFT-AND approach by BaezaYates and Gonnet (CACM 35(10), 1992) to the matching problem for network expressions, which are regular expression...
