The development of computer technologies gives rise to a revolution in all socio-cultural practices, including arts and literature. In terms of poetry, for example, readers have now access to new lyrical experiences either through emerging poetic genres or through so-far unimagined approaches to traditional ones. Lots of research has been done in the field of Computer Science on technical issues of computer-generated poetry, but little on the aesthetic impacts of having poems produced by machines. Therefore, we herein propose a multidisciplinary literary analysis of poems produced by the tool Peter’s Haiku Generator, in order to discuss how software design decisions can affect literary aspects and the aesthetic effects of those poems.
