This paper argues that comparatives can be structurally analyzed on the basis of syntactic information alone via a strictly surface-based grammar. Such a grammar is given in Ryan 5 based on the co-representational model of Kac 1 . While the grammar does not define a parsing algorithm per se it nonetheless expresses regularities of surface organization and its relationship to semantic interpretation that an adequate parser would be expected to incorporate. This paper will discuss four problem areas in the description of comparatives and will outline the sections of the grannar of 5 that apply to them. The central problem in parsing comparatives Involves identifying the arguments of comparative predicates and the relations borne by these arguments to Such predicates. A corepresentational grammar is explicitly designed to assign predicate-argument structure to sentences on the basis of their surface syntactic organization. SEC. 2 comparative predicates An Initial assumption underlying the proposed analysis of comparatlves 1s that the comparative elements such as more faster more spacious are syntactically akin to predicates and thus that the principles applying to predicate-argument structure extend to them. Each comparative element will accordingly have arguments Subject and Object assigned to it and comparative predications will also be analyzed as being 1n relations of subordination or Superordination with other predications 1n the sentences In which they appear. For example in 1 below the comparative predicate richer will have both a simple NP Subject and a simple NP Object 1 John knows doctors richer than Tom SUBJ T OBJ The referent of OBJ richer i.e. Tom is to be .
