  abstract = {This paper describes a method of semi-automatically acquiring an English HPSG grammar from the Penn Treebank. First, heuristic rules are employed to annotate the treebank with partially-specified derivation trees. Lexical entries are automatically extracted from the annotated corpus by inversely applying schemata to partially-specified derivation trees.},
