Abstract This chapter provides basic data about Language Technology for the Czech language. After a brief introduction with general facts about the language (history, linguistic features, writing system, dialects), we touch upon Czech in the digital sphere. The main achievements in the field of NLP are presented: important datasets (corpora, treebanks, lexicons etc.) and tools (morphological analyzers, taggers, automatic translators, voice recognisers and generators, keyword extracters etc).
