This paper describes results achieved in a project which addresses the issue of how the gap between unificationbased grammars as a scientific concept and real world applications can be narrowed down 1 . Applicationoriented grammar development has to take into account the following parameters: Efficiency: The project chose a so called 'lean' formalism, a termencodable language providing efficient term unification, ALEP. Coverage: The project adopted a corpusbased approach. Completeness: All modules needed from text handling to semantics must be there. The paper reports on a text handling component, Two Level morphology, word structure, phrase structure, semantics and the interfaces between these components. Mainstream approach: The approach claims to be mainstream, very much indebted to HPSG, thus based on the currently most prominent and recent linguistic theory. The relation (and tension) between these parameters are described in this paper.
