Abstract
Case systems abound in natural language processing. Almost any
attempt to recognize
and uniformly represent relationships within a clause – a unit at
the centre of any linguistic system
that goes beyond word level statistics – must be based on
semantic roles drawn from a small,
closed set. The set of roles describing relationships between a verb and
its arguments within a
clause is a case system. What is required of such a case system? How does
a natural language
practitioner build a system that is complete and detailed yet practical
and natural? This paper
chronicles the construction of a case system from its origin in English
marker words to its
successful application in the analysis of English text.
