Top-K Color Queries for Document Retrieval
In this paper we describe a new efficient (in fact optimal) data structure for the top-K color problem. Each element of an array A is assigned a color c with priority p(c). For a ...

Ziv Lempel Compression of Huge Natural Language Data Tries Using Suffix Arrays
We present a very efficient, in terms of space and access speed, data structure for storing huge natural language data sets. The structure is described as LZ (Ziv Lempel) compresse...
