Metaphor signalling constructions in discourse related to the experience of depersonalization/derealization

ABSTRACT

In this study a systematic analysis of signaled metaphor is undertaken in naturally occurring discourse from an online forum relating to the experience of depersonalization/derealization, which has a specific relationship with metaphor. While it is relatively easy to locate pre-identified metaphor source terms in such large text corpora, finding singular metaphor that may express subjective experience is recognized as a difficult but important task, which signals of metaphor may support. It is vital to accurately represent, such discourse, rather than only impose pre-defined knowledge, in order that ethical concerns such as exclusion, demographic misrepresentation, and bias confirmation, may be addressed. It is shown that different signals of metaphor investigated perform different functions in relation to metaphor, with many of them supporting use of idiosyncratic metaphor that appears to express the subjective experience of forum participants. Analysis of nouns across all sentences identified as containing signaled metaphor yields previously unknown terms that are typically associated with metaphor in this context, via a method that is grounded in the data. In addition, the summary list of metaphor signaling constructions may support further such investigations in large text corpora.
