The Role of PRED in LFG+Glue

In this paper, I argue that standard, co-descriptional glue semantics provides no clear and satisfactory role for the traditional PRED-features of LFG, due to the fact that the linear logic of glue semantics does the work of the Completeness and Coherence Constraints. But then I show that a reduced but significant role for PRED-features can be found in an alternative `Description-by-Analysis' (DBA) formulation, proposed in Andrews (2007), and independently developed for the XLE (Crouch, p.c.), although no longer used.

The DBA formulation is argued to be superior in various respects, and some constraints are proposed to cause the DBA approach to approximate some of the empirically justifiable aspects of the behavior of the co-descriptional formulation.
