Computational linguistic creativity can primarily be aimed at creating systems that either are creative themselves (e.g., generate poetry, generate screen plays, write song lyrics, produce analogies or metaphors) or try to understand creativity (e.g., identify sarcasm, understand humour or interpret rhymes).
A master thesis project in the field could concentrate on one or several of these different aspects of computational linguistic creativity (e.g., generate and evaluate computational poetry, translate on-line jokes between two languages, or generate plot twists in movies).
