Generation of anaphoric noun phrases and their coreferential properties
This paper investigates the generative processes involved in the formation of noun phrases (NPs) from an existing clause in a discourse. A speaker or writer is able to generate a range of NPs from a stated clause to co-refer to the different semantic units of the clause by combining the various primitive components. These generative processes can be grouped into either predicate-deletion or normalization. We use relations defined by Levi (Levi1973) as a basis to define constraints used in the formation of NPs by predicate-deletion and empirically determine the conformance level of these constraints with natural discourses. For the normalization process, we argue that the inflicted morpheme's anaphoric properties can be characterized by their suffixes. We also show that, these anaphoric properties are independent of the choice between subjective and objective modifiers. The anaphoric properties of suffix-based morphemes is also empirically investigated for conformance levels, and the results are encouraging.
