Analysis of a corpus of queries to a statistical database has shown considerable variation in the location and order of modifiers in complex noun phrases. Never- theless, restrictions can be defined on nominal mod- ification because of certain correspondences between nominal modifiers and the role they fulfill in a statisti- cal database, notably that the names of database tables and columns, and values of columns, are all determined by the modifiers. These restrictions are described. In- corporating these restrictions into Head-Driven Phrase Structure Grammar (HPSG) has caused us to examine the treatment of nominal modification in HPSG. A new treatment is proposed and an implementation within an HPSG based natural language front-end to a statistical database is described.
