I've done previous work on haiku generation. This generator uses Markov chains trained on a corpus of non-haiku poetry, generates haiku one word at a time, and ensures the 5-7-5 structure by backspacing when all the possible next words would violate the 5–7–5 structure. This isn't unlike what I do when I'm writing a haiku. I try things, count out the syllables, find they don't work and go back. It feels more like brute force than something that actually understands what it means to write a haiku.

SAPPORO – The development of artificial intelligence software that can write haiku based just on images is underway, with researchers hoping the project will improve how technology understands human emotion. A team of researchers and software developers led by Hidenori Kawamura, a 44-year-old professor at Hokkaido University's graduate school, is aiming to create AI that can analyze a vast amount of poetry to generate a haiku written about a subject or scene. The AI has been learning masterpieces composed by renowned Japanese poets such as Kobayashi Issa (1763-1827) and Masaoka Shiki (1867-1902), and analyzing pictures picked by volunteers that correspond to the poems. According to the team, the AI checks whether it is following structural rules and is using appropriate seasonal references. Haiku are defined by the use of a set number of syllables and traditionally use words that describe the season in which the work is set.
