Abstract

We present an integrated architecture for word-level and sentence-level processing in a unification-based paradigm. The core of the system is a CLP implementation of a unification engine for feature structures supporting relational values. In this framework an HPSG-style grammar is implemented. Word-level processing uses X2MORF, a morphological component based on an extended version of two-level morphology. This component is tightly integrated with the grammar as a relation. The advantage of this approach is that morphology and syntax are kept logically autonomous while at the same time minimizing interface problems.
