Some advantages of Davis' formalisation over Jackendoff's are listed
below.
- Relation arguments are associated with specific, consistent
entailments.
- It takes advantage of inheritance to capture relationships
among semantic relations and to effectively group relations
together in various ways (where one relation can belong to several
`groups' via multiple inheritance).
- The formalism can be directly inserted into the grammar
formalism of HPSG, leaving in place a framework for parsing
sentences and building up a representation of their semantics.
For these reasons I will build on Davis' formalisation, augmenting it
with certain representational elements. Several additions have been
motivated in the previous section on the basis of Jackendoff's
proposals. I will suggest several more here which do not derive from
Jackendoff's work but from the issues to be examined in this thesis.
My goal in proposing these extensions is to extend the functionality
of the representation language to allow for modeling of interactions
between lexical semantic information in compositional semantics, as
well as the interactions with syntactic realisation.
