Unification-based Paradigmatic Morphology
Martine Smets (University of Sussex)
This paper presents a language to express inflectional morphology.
The language assumes a feature-based representation of the lexicon.
The lexicon is organized into three components:
The morphological component is organized into two kinds of
paradigms: helping paradigms and main paradigms. Helping paradigms
define underspecified words, relating morphosyntactic features to
their phonological realization. Main paradigms define completely
specified inflected words, by unifying entries of helping paradigms
and relating the result of unification to stems of the lexicon.
The definition of the phonology attribute of words is inspired by Bird
and Klein (1993). Its value is an object of type "phonology", itself
constrained by relevant attributes. As Bird and Klein (1993) shows,
this approach allows to account for concatenative as well as
non-concatenative types of morphology.
the hierarchy of types, capturing generalizations about words (it is
inspired from the organization of the lexicon in the HPSG framework);
the morphological component;
the lexicon of stems.
This language has been implemented in SICStus Prolog.
