The development of a database of Czech derived words is described, focusing on linguistic aspects of this task. In Czech, which is a Slavic language with both rich inflectional and derivational morphology, derivation is the most frequent and most productive word-formation process.
The database of Czech derived words was designed as a lexical network, which consists of lexemes and derivational relations (links) between them, oriented from the base to the derived word. The derivational relations were processed automatically under a thorough manual supervision in order to ensure efficiency and consistency on the one hand and theoretical adequacy on the other.
