Unfortunately, for reasons unrelated to the authors, the Evolutionary Poster Composer (version 2.0) is not available online. We are trying to get it online as soon as possible.

Evolutionary Poster Composer (version 1.0) is a web system that generates letterpress-inspired typographic posters using, as content, tweets posted online. The proposed system employs Natural In this project, Language Understanding approaches to recognise the emotions, the sentiments, and the colours associated with the content. Also, the system employs an Evolutionary Computation approach to generate and evolve a population of poster designs. The outputs are evaluated according to their legibility, aesthetics, and semantics, throughout an automatic fitness assignment hybrid scheme that combines a hardwired fitness function part with a multi-objective optimisation approach part.
