We investigate the utility of supertag infor- mation for guiding an existing dependency parser of German. Using weighted con- straints to integrate the additionally avail- able information, the decision process of the parser is influenced by changing its preferences, without excluding alternative structural interpretations from being con- sidered. The paper reports on a series of experiments using varying models of su- pertags that significantly increase the pars- ing accuracy. In addition, an upper bound on the accuracy that can be achieved with perfect supertags is estimated.
