A compressed full-text self-index occupies space close to that of the compressed text and simultaneously allows fast pattern matching and random access to the underlying text. Among the best compressed self-indexes, in theory and in practice, are several members of the FM-index family. In this paper, we describe new FM-index variants that combine nice theoretical properties, simple implementati...

This paper presents a tunable index compression scheme for supporting time-travel phrase queries over large versioned corpora such as web archives. Support for phrase queries makes maintenance of word positions necessary, thus increasing the index size significantly. We propose to fuse the word positions in many neighboring versions of a document, and thus exploit the typically high level of re...

Data collections are traditionally stored as individually compressed files. Where the files have a significant degree of similarity, such as genomes, incremental backup archives, versioned repositories, and web archives, additional compression can be achieved using references to matching data from other files in the collection. We describe compression using long-range or inter-file similarities...

Compression has been used typically to save disk space and bandwidth. However, from a decade ago, a new family of data structures allows applying compression to save space in main memory as well. The so-called self-indexes are an example of these new structures. They can store a text in space proportional to that of the compressed version of the same text, and at the same time, they allow searc...

Indexing plays an important role for storing and retrieving the data in Information Retrieval System (IRS). Inverted Index is the most frequently used indexing structure in IRS. In order to reduce the size of the index and retrieve the data efficiently, compression schemes are used, because the retrieval of compressed data is faster than uncompressed data. High speed compression schemes can imp...

The void index is a relative quantity measuring the position of the current void ratio of a clay against the void ratios of the clay at two specific vertical effective stresses (i.e., σ v ′ = 100 kPa and σ v ′ =1000 kPa). Based on this concept, a simple systematic tool is proposed for estimating the compression behaviour of reconstituted clays over a wide range of stresses and water contents. F...
