Towards Licensing of Adverbial Noun Phrases in HPSG

This paper focuses on aspects of the licensing of adverbial noun phrases (AdvNPs) in the HPSG grammar framework. In the first part, empirical issues will be discussed. A number of AdvNPs will be examined with respect to various linguistic phenomena in order to find out to what extent AdvNPs share syntactic and semantic properties with non-adverbial NPs. Based on empirical generalizations, a lexical constraint for licensing both AdvNPs and non-adverbial NPs will be provided. Further on, problems of structural licensing of phrases containing AdvNPs that arise within the standard HPSG framework of Pollard and Sag (1994) will be pointed out, and a possible solution will be proposed. The objective is to provide a constraint-based treatment of NPs which describes non-redundantly both their adverbial and non-adverbial usages. The analysis proposed in this paper applies lexical and phrasal implicational constraints and does not require any radical modifications or extensions of the standard HPSG geometry of Pollard and Sag (1994). Since adverbial NPs have particularly high frequency and a wide spectrum of uses in inflectional languages such as Polish, we will take Polish data into consideration.
