Adding preferences to CUF

We discuss the problem of associating grammars written in CUF DD93] with preference information of the sort which has proved useful in the development of large scale grammars like the Alvey Natural Language Tools Grammar GBCB89]. We show a way to embed a useful part of the functionality of the Xerox part of speech tagger Kup92] into the framework of CUF, developing a design for a version which has the appropriate facilities for the handling of numeric data. On the basis of this design we speculate about the prospects of including other preference-based mechanisms within grammar encoded in CUF, and draw preliminary conclusions about the nature of this enterprise.
