This paper presents a semantic interpretation of adjectival modification in terms of the Generative Lexicon. It highlights the elements which can be borrowed from the GL and develops limitations and extensions. We show how elements of the Qualia structure can be incorporated into semantic composition rules to make explicit the semantics of the combination adjective + noun. | A Generative Lexicon Perspective for Adjectival Modification Patrick Saint-Dizier IRIT-CNRS Université Paul Sabatier 118 route de Narbonne F-31062 Toulouse Cedex France stdizier@ Abstract This paper presents a semantic interpretation of adjectival modification in terms of the Generative Lexicon. It highlights the elements which Coin be borrowed from the GL and develops limitations and extensions. We show how elements of the Qualia structure can be incorporated into semantic composition rules to make explicit the semantics of the combination adjective -I- noun. 1 Aims Investigations within the generative perspective aim at modelling by means of a small number of rules principles and constraints linguistic phenomena at a high level of abstraction level which seems to be appropriate for research on multi-linguism and language learning. Among works within the generative perspective one of the most innovative is the Generative Lexicon GL Pustejovsky 91 95 which introduces an abstract model opposed to sense enumeration lexicons. The GL is based 1 on the close cooperation of three lexical semantic structures the argument structure the aspectual structure and the Qualia structure with four roles Telic Agentive Constitutive and Formal 2 on a detailed type theory and a type coercion inference rule and 3 on a refined theory of compositionality. The Generative Lexicon investigates the problem of polysemy and of the multiplicity of usages from a core sense of a lexeme and show s how these usages can be analyzed in terms of possible type shiftings . the type expected by the core usage. Type shifting is modelled by a specific inference mechanism type coercion. In this paper the following points are addressed Generative systems require a clear analysis of the notions of word-sense and of sense delimitation. Depending on the strategy adopted . large number of narrow senses for a lexeme as in WordNet or very few but large senses as in many Al works the nature and the
