Harnessing NLG to create Finnish poetry automatically

This paper presents a new, NLG based approach to poetry generation in Finnish for use as a part of a bigger Poem Machine system the objective of which is to provide a platform for human computer co-creativity. The approach divides generation into a linguistically solid system for producing grammatical Finnish and higher level systems for producing a poem structure and choosing the lexical items used in the poems. An automatically extracted open-access semantic repository tailored for poem generation is developed for the system. Finally , the resulting poems are evaluated and compared with the state of the art in Finnish poem generation.
