+
 **Xcdat** is a C++17 header-only library of a fast compressed string dictionary based on an improved double-array trie structure described in the paper: [Compressed double-array tries for string dictionaries supporting fast lookup](https://doi.org/10.1007/s10115-016-0999-8), *Knowledge and Information Systems*, 2017, available [here](https://kampersanda.github.io/pdf/KAIS2017.pdf).
