Backwards Search in Context Bound Text Transformations
—The Burrows-Wheeler Transform (BWT) is the basis for many of the most effective compression and selfindexing methods used today. A key to the versatility of the BWT is the abili...

Linear Suffix Array Construction by Almost Pure Induced-Sorting
We present a linear time and space suffix array (SA) construction algorithm called the SA-IS algorithm. The SA-IS algorithm is novel because of the LMS-substrings used for the pro...

Generating labels from clicks
The ranking function used by search engines to order results is learned from labeled training data. Each training point is a (query, URL) pair that is labeled by a human judge who...
