Engineering a Distributed Full-Text Index

We present a distributed full-text index for big data applications in a distributed environment. The index can be used to answer different types of pattern matching queries (existential, counting and enumeration) and also be extended to answer document retrieval queries (counting, retrieve and top-k). We also show that succinct data structures are indeed useful for big data applications, as the...

Huffman-based code compression techniques for embedded systems

Increasing embedded systems functionality causes a steep increase in code size. For instance, more than 60MB of software is installed in current state-of-the-art cars [9]. It is often challenging and cumbersome to host vast amount of software in an efficient way within a given hardware resource budget of an embedded system. This may be done by using code compression techniques, which compress t...

The FM-Index: A Compressed Full-Text Index Based on the BWT

In this talk we address the issue of indexing compressed data both from the theoretical and the practical point of view. We start by introducing the FM-index data structure [2] that supports substring searches and occupies a space which is a function of the entropy of the indexed data. The key feature of the FM-index is that it encapsulates the indexed data (self-index) and achieves the space r...
