The LZ-index: A Text Index Based on the Ziv-Lempel Trie

By Gonzalo Navarro

Abstract

Let a text of u characters over an alphabet of size oe be compressible to n symbols by the LZ78 or LZW algorithm. We show how to build a data structure, called the LZ-index, based on the Ziv-Lempel trie that takes 4n log2 n(1 + o(1)) bits of space (that is, 4 times the entropy of the text) and reports the R occurrences of a pattern of length m in worst case time O(
