Abstract:
Semantic representations ideally provide an abstraction which allows
generalisations to be made across very different surface forms and different
syntactic formalisms. But deriving conventional semantic representations
requires more information than can be extracted from morphology and syntax,
even by deep grammars. The standard way of dealing with this is to use
underspecified semantic representations, which can, in principle, be
monotonically enriched to provide deeper semantics which inference engines can
work with. However, researchers often work directly with the underspecified
representations, using a variety of operations to process them. In this
paper, I will discuss 'matching', 'merging' and 'munging' operations in the
context of the (Robust) Minimal Recursion Semantics approach and give an
overview of some of the uses to which they have been put.
