This paper reports on the latest rejuvenation of AMAZON, a structuralist parser for Dutch written sentences. Unlike older versions, the new AMAZON parser has been developed in a modular organization, with an empirical cycle containing evaluations on corpus material. This methodology facilitates the development by separate researchers, and it gives more insight into the actual performance of the parser, providing a useful means of measuring the improvement during development. In this paper, the evaluation method, and its outcome, is presented in general. As a more specific case study, the implementation of a separate module for interruption constructions is discussed.
