Core Concepts
Direct objects of verbs used as metaphors tend to have lower degrees of concreteness, imageability, and familiarity, and metaphors are more likely to be used in emotional and subjective sentences.
Abstract
This study aimed to verify existing claims about metaphors by leveraging large-scale automatic metaphor identification. The key findings are:
Concreteness, Imageability, and Familiarity of Objects:
The direct objects of verbs used as metaphors tend to have lower degrees of concreteness, imageability, and familiarity compared to non-metaphorical usages. This supports the claims that the target domain in conceptual metaphors is less concrete, imageable, and familiar.
Emotion and Subjectivity:
Sentences with emotional polarity, especially positive polarity, show significantly higher metaphor usage rates than neutral sentences. This supports the claim that metaphors are more likely to be used in emotional sentences.
Sentences with a first-person subject, which are more likely to express subjectivity, have significantly higher metaphor usage rates than sentences with a third-person subject. This supports the claim that metaphors are more likely to be used in sentences expressing subjective content.
The study leveraged a large corpus of English sentences and applied an automatic metaphor identification model to analyze the properties of metaphorical and non-metaphorical examples. The findings provide empirical evidence to verify several existing claims about the nature of metaphors in language.
Stats
The direct objects in metaphorical examples have lower concreteness scores than those in non-metaphorical examples.
Sentences with positive emotional polarity have a higher metaphor usage rate than neutral sentences.
Sentences with a first-person subject have a higher metaphor usage rate than sentences with a third-person subject.
Quotes
"Metaphors can paint a richer and more detailed picture of our subjective experience than can be expressed by literal language."
"Subjective emotional experience is the essence of emotion, and objective manifestations in behavior, body, or brain physiology are at best indirect indicators of these internal experiences."
