Abstract
The implementation of a unification-based lexicon is dis- cussed as well as the morphological rules needed for mapping between the lexicon and grammar. It is shown how different feature usages can be utilized in the implementation to reach the intended surface word-form matches, with the correct feature settings. A novelty is the way features are used as binary signals in the compositional morphology. Finally, the lexicon coverage of the closed-class words and of the different types of open-class words is evaluated.
