Prosodic Inheritance (PI) morphology provides uniform treatment of both concatenative and non-concatenative morphological and phonological generalisations using default inheritance. Models of an extensive range of German Umlaut and Arabic intercalation facts, implemented in DATR, show that the PI approach also covers 'hard cases' more homogeneously and more extensively than previous computational treatments. | PROSODIC INHERITANCE AND MORPHOLOGICAL GENERALISATIONS Sabine Reinhard Dafydd Gibbon Unlversitat Bielefeld Fakultat fur Linguistik und Literaturwissenschaft _ p 8640 D-4800 Bielefeld 1 email reinhard@lilil 1 . gibbon@lili 11 . ABSTRACT Prosodic Inheritance PI morphology provides uniform treatment of both concatenative and non-concatenatlve morphological and phonological generalisations using default inheritance. Models of an extensive range of German Um aut and Arabic intercalation facts Implemented in DATR show that the PI approach also covers hard cases more homogeneously and more extensively than previous computational treatments. 1. INTRODUCTION Computational models of sentence syntax are increasingly based on well-defined linguistic theories and implemented using general formalisms by contrast morphology and phonology in the lexicon tend to be handled with tailor-made hybrid formalisms selected for properties such as finite state compilability object orientation default inheritance or procedural efficiency. The linguistically motivated Prosodic Inheritance PI model with defaults captures morphotactic and morphophonological generalisations in a unified declarative formalism and has broad linguistic coverage of both concatenative morphology and the notorious hard cases of non-concatenative morphology. This paper Integrates the PI concepts underlying previous descriptions of German Umlaut Reinhard 1990a 1990b Bantu tone morphology and Arabic C-V intercalation Gibbon 1990 Umlaut and intercalation are treated here. PI descriptions are currently implemented In a DATR dialect Gibbon 1989 for DATR cf. Evans Gazdar 1989 1990 1989a 1989b DATR was chosen for its syntactic simplicity and its explicit formal semantics. 2. INHERITANCE AND NON-CONCATENATIVE MORPHOLOGY Morphological generalisations are of three basic kinds morphotactic the combinatorial principles of word composition in terms of immediate dominance ID relations morpho-semantic
