Sentences from a source language having first rules of grammar are translated into a target language having second rules of grammar; the resulting sentences are meaningful but ungrammatical. The ungrammatical sentences are changed into grammatical sentences by a method that includes identifying grammar markers and grammar marker patterns in the translated put ungrammatical sentence. A first database includes grammar rules and is consulted for each grammar marker that appears in the ungrammatical sentence. A second database includes self-correction rules and is consulted for each grammar marker pattern that appears. The grammar rules and self-correction rules are applied by a correction scheme. The resulting sentences are substantially perfectly grammatical.
