Abstract. In this paper we present an adaptation of two Czech syntactic analyzers Synt and SET for Slovak language. We describe the transformation of Slovak morphological tagset used by the Slovak development corpora skTenTen and r-mak-3.0 to its Czech equivalent expected by the parsers and modifications of both parsers that have been performed partially in the lexical analysis and mainly in the formal grammars used in both systems. Finally we provide an evaluation of parsing results on two datasets – a phrasal and dependency treebank of Slovak.
