This paper presents a Constraint Grammar-based method for changing the tokenization of existing annotated data, establishing standard space-based ("atomic") tokenization for corpora otherwise using MWE fusion and contraction splitting for the sake of syntactic transparency or for semantic reasons. Our method preserves ingoing and outgoing dependency arcs and allows the addition of internal tags and structure for MWEs. We discuss rule examples and evaluate the method against both a Portuguese treebank and live news text annotation.
