The prologue

Nowadays, the available data is constantly growing and changing. It is safe to assume that this tendency will persist in the next years. With the increasing amount of data, process such data in an efficient way is a (beautiful) challenge. Several research lines have emerged in the last years to face this challenge, such as, full-text indexes, compact data structures, parallel construction of space efficient data structures, among others.

The objective of this site is to provide datasets to support the research and teaching on compact data structures and related fields. We provide a set of real-world and artificial datasets of graphs, trees and balanced parentheses. If you are looking for datasets of text, you can visit the Pizza&Chili site.
