Compression of dictionary
Kuřík, Stanislav ; Lánský, Jan (advisor) ; Žemlička, Michal (referee)
This thesis deals with improving the existing dictionary compression method TD3. This method is based on encoding of the trie data structure, which is pre x tree serving as a storage of an associative array in which strings are used as keys. TD3 encodes each node using Elias Gamma and Delta codes. First enhancement over TD3 is replacing Elias codes with static and adaptive Hu man coding. Next improvements present a di erent way the node information are coded. The new TD4 method was benchmarked on a huge corpus and this thesis comprises among others an evaluation of the measured results.
