  The paper defends the notion that semantic tagging should be viewed as more
than disambiguation between senses. Instead, semantic tagging should be a first
step in the interpretation process by assigning each lexical item a
representation of all of its systematically related senses, from which further
semantic processing steps can derive discourse dependent interpretations. This
leads to a new type of semantic lexicon (CoreLex) that supports underspecified
semantic tagging through a design based on systematic polysemous classes and a
class-based acquisition of lexical knowledge for specific domains.
