Description The aim of the paper is to present results of the automatic analysis of some regular derivational types in Czech. In section 2 we briefly characterize the last obtained results in formal morphology of Czech (inflection) and its automatic processing as well as derivational morphology (word formation). In section 3 we show how the relations between word base and derived word can be described formally. In section 4 we explain how changes on the formal level correspond to semantic relations between related words (motivation relations). In section 5 we deal with the examples showing how the particular rules can be formulated and used in the new version of the software tool Deriv (derivational interface) that allows us to test derivational rules on the large machine dictionary of Czech stems. In section 6 we present particular results: rules which describe some selected derivational types. Finally, in section 7 we summarize the results obtained so far in the course of testing the software tool Deriv and indicate the further possibilities of its use.
