Grammar extraction in deep formalisms has received remarkable attention in recent years. We recognise its value, but try to create a more precision-oriented grammar, by hand-crafting a core grammar, and learning lexical types and lexical items from a treebank. The study we performed focused on German, and we used the Tiger treebank as our resource. A completely hand-written grammar in the framework of HPSG forms the inspiration for our core grammar, and is also our frame of reference for evaluation.
