Particularly, electronic dictionary-thesauruses, semantic dictionaries are one of them. Dictionary-thesaurus formation structure for Uzbek language, transferring the terminological dictionary into the e-version and implementing rules for establishing semantic relations between words where it gives a chance to establish automation linguistic processes of dictionary-thesauruses, which is the foundation of linguistic databases.
