| Challenge: | Existing approaches to generate metaphors rely on template-based or rule-based knowledge, which constrains the diversity of generated metaphors. |
| Approach: | They propose a neural approach to metaphor generation that uses wiki corpus to extract metaphorically used verbs and train a language model. |
| Outcome: | The proposed approach generates metaphors with good readability and creativity using wiki corpus and automatic metrics and human evaluations. |
