Distribution-Aware Compressed Full-Text Indexes
Abstract. In this paper we address the problem of building a compressed self-index that, given a distribution for the pattern queries and a bound on the space occupancy, minimizes ...

A Unified Algorithm for Accelerating Edit-Distance Computation via Text-Compression
The edit distance problem is a classical fundamental problem in computer science in general, and in combinatorial pattern matching in particular. The standard dynamic-programming s...

Adding Compression to Block Addressing Inverted Indexes
Inverted index compression, block addressing and sequential search on compressed text are three techniques that have been separately developed for e cient, low-overhead text retrie...

An Index for Two Dimensional String Matching Allowing Rotations
We present an index to search a two-dimensional pattern of size m m in a two-dimensional text of size n n, even when the pattern appears rotated in the text. The index is based on ...

Approximate String Matching with Lempel-Ziv Compressed Indexes
Abstract. A compressed full-text self-index for a text T is a data structure requiring reduced space and able of searching for patterns P in T. Furthermore, the structure can repro...
