The hyperonym problem revisited
Manfred Stede · 2000
When a lexical item is selected in the language production process, it needs to be explained why none of its superordinates gets selected instead, since their applicability conditions are fulfilled all the same. This question has received much attention in cognitive modelling and not as much in other branches of NLG. This paper describes the various approaches taken, discusses the reasons why they are so different, and argues that production models using symbolic representations should make a distinction between conceptual and lexical hierarchies, which can be organized along fixed levels as studied in (some branches of) lexical semantics.
