Black Holes and White Rabbits: Metaphor Identification with Visual Features
Metaphor is pervasive in our communication, which makes it an important problem for natural language processing (NLP) Numerous approaches to metaphor processing have thus been proposed, all of which relied on linguistic features and textual data to construct their models. Human metaphor comprehension is, however, known to rely on both our linguistic and perceptual experience, and vision can play a particularly important role when metaphorically projecting imagery across domains. In this paper, we present the first metaphor identification method that simultaneously draws knowledge from linguistic and visual data. Our results demonstrate that it outperforms linguistic and visual models in isolation, as well as being competitive with the best performing metaphor identification methods, that rely on hand crafted knowledge about domains and perception.
