Abstract
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.
