Knowledge Identification and Metaphor
Roger Browse
Abstract
This paper deals with the organization of semantic properties of nouns and their use in the
determination of case role acceptability. By only examining simple hierarchical inclusion
properties, natural language systems have been unable to deal with metaphoric language use. The
research outlined here is an investigation into the use of general methods for the determination of
case fulfilment. These methods include a more flexible use of the hierarchical relationships
represented in the system, and the methods also use the contents of other case-frames. These
methods develop the degree of freedom necessary for the acceptance of metaphoric language.
Other interesting properties of the system are described which also argue in favour of this
approach to the organization of semantic knowledge.
