....productivity. Nothing so far accounts for the fact that the prototype in e#ect provides a template for new members of a class. As it is usually presented, the HPSG hierarchical lexicon is completely closed: all lexical types are explicitly listed and located within the type hierarchy. However, as [Koenig Jurafsky, 1994] observe, such type hierarchies make it di#cult to model productivity. In a closed hierarchy, every type is listed, whether or not its existence is predictable. Since no distinction is made between irregular types and regular types that follow a productive pattern, one must appeal to some external ....

....redundant, essentially stipulating that stem final t s alternate in Finnish. The other approach, using lexical typing and analogy, is the one I will advocate here. On this approach, lexical items are sorted by phonological specification into phonological types, as shown below (on types, see e.g. Koenig Jurafsky 1994, Orgun 1996 and references therein) 67) Final consonant Final voiceless coronal plosive Other. Final t Final T 0 100 This sorting over known underlying forms serves as the basis for analogy, the method used to come up with underlying representations for new surface forms that ....

....of lexical rules has been discussed extensively in recent literature. Copestake 1992 has integrated them into the hierarchical structure of the lexicon, so that subsumption relationships between lexical rules can be expressed. Krieger Nerbonne (1993) Kathol (1993) Riehemann (1993) and Koenig Jurafsky (1994) have worked on various ways of eliminating the need for a lexical rule mechanism. There has also been an implementation in HPSG of a word syntactic approach. Krieger Nerbonne 1993 and Krieger 1993 use a phrase structural approach to morphology to illustrate their inheritance lexicon. They ....
