System Demonstration

Our system demonstration based on the CM-BART model is now available, try it out!

Models

This paper defines two models for metaphor generation based on conceptual mappings: CM-Lex and CM-BART. CM-Lex uses no training data, and works at the word level, while CM-BART is a BART-based seq2seq model.

CM-BART will generally yield better performance, and doesn't require knowing which word to change. If you know which word needs to be changed, CM-Lex may be appropriate.

These models each have their own directory and requirements. See their respective READMEs for more details.
