Abstract
This paper presents the first computationally-derived scalar measurement of metaphoricity. Each input sentence is given a value between 0 and 1 which represents how metaphoric that sentence is. This measure achieves a correlation of 0.450 (Pearson’s R, p <0.01) with an experimental measure of metaphoricity involving human participants. While far from perfect, this scalar measure of metaphoricity allows different thresholds for metaphoricity so that metaphor identification can be fitted for specific tasks and datasets. When reduced to a binary classification evaluation using the VU Amsterdam Metaphor Corpus, the system achieves an F-Measure of 0.608, slightly lower than the comparable binary classification system’s 0.638 and competitive with existing approaches.

Language-Independent Ensemble Approaches to Metaphor Identification
Dunn J; Beltran de Heredia J; Burke M; Gandy L; Kanareykin S; Kapah O; Taylor M; Hines D; Frieder O; Grossman D; Howard N; Koppel M; Morris S; Ortony A; Argamon S (2014)True natural language understanding requires the ability to identify and understand metaphorical utterances, which are ubiquitous in human communication of all kinds. At present, however, even the problem of identifying ... -
How linguistic structure influences and helps to predict metaphoric meaning
Dunn J (Walter de Gruyter GmbH, 2013)This paper argues that two properties of the linguistic structure of an utterance influence and partially determine whether the utterance has a metaphoric meaning that results in a stable interpretation: (i) degree of ... -
What Metaphor Identification Systems Can Tell Us About Metaphor-in-Language
Dunn J (2013)This paper evaluates four metaphor identification systems on the 200,000 word VU Amsterdam Metaphor Corpus, comparing results by genre and by sub-class of metaphor. The paper then compares the rate of agreement between ...
