Scope relations below the word level
Markus EggUniversity of Groningen
Topic of the presentation are semantic scope relations below the word
level. Due to these relations, the semantic and the syntactic
structure of linguistic expressions can differ considerably, which
makes them a challenge for the syntax-semantics interface, for the
theoretical question of how to define the relation between syntactic
and semantic structure as well as for semantic construction as a
practical task in an NLP system.
To cite a simple example for such an expression, consider modified
indefinite pronouns like everyone in this room; intuitively, the PP
takes scope between every- and -one, which incompatible with the
syntactic (surface) structure.
I will compare several interface strategies that are proposed in the
literature for their way of handling these scope relations below the
word level. The strategies are cast in Generative Grammar,
underspecification formalisms, LFG, and LTAG.
