Abstract
Metonymy is the figure of speech where "we are using one entity to
refer to another that is related to it", according to a well-known
definition by Lakoff and Johnson (1980). Typical examples are "The ham
sandwich is waiting for his check" or "I read Shakespeare". Metonymy
is pervasive in natural language and its importance has been shown for
anaphora resolution, machine translation and question answering.
Although several automatic metonymy resolution procedures have been
developed in the past, they share the following drawbacks: they are
scarcely or not at all evaluated, the evaluation often uses toy texts
or is performed using only the intuition of the developer as
comparison standard, the methods use extensive hand-modelled lexical
or world knowledge and are not robust.
I, therefore, propose metonymy resolution procedures that are firmly
based in corpus investigations and human annotation standards and use
statistical methods comparable to methods used in word sense
disambigation.
In this talk I will present: firstly, the, to my knowledge, first
metonymy annotation scheme which has been rigorously evaluated for
reliability on natural language texts and an overview of the problems
associated with metonymy annotation; secondly, a corpus annotated with
this annotation scheme; thirdly, a novel view of metonymy resolution
as a classification task using the categories of this annotation
scheme as well as the experimental results of some statistical
classification methods (decision lists, naive Bayes) using various
feature types for metonymy recognition.
