abstract = "Many works have been done in an effort to create
systems for automatic generation of creative culinary
recipes. Although most of them are related to the
recipe ingredient lists, few works have been done to
evaluate and generate the preparation steps of culinary
recipes. This work proposes the use of statistical
Language Models, as well as the perplexity metric, for
the generation of culinary recipes. In this work, we
also developed a system for automatic generation of
creative culinary recipes using two approaches: one
based on a genetic programming algorithm guided by the
proposed language model; and the other based on a
decomposition of existing recipes and recomposition of
new recipes through a genetic algorithm guided by the
proposed language model. This second approach achieved
the best results. For this approach, a total of 6
recipes were generated to evaluate, through an online
survey, the influence of the Language Model in the
generation of recipes with better use of secondary
ingredients, oils and seasonings, throughout the
preparation steps. In the comparison between these two
groups of recipes, the respondents considered the
recipes generated using the language model as having
the best quality, presenting an average evaluation of
63.percent of the scale (i.e. between medium and good
use of oils and seasonings compared to recipes from the
other group). In addition, a recipe from this approach
was cooked and tasted for taste assessment, obtaining
an average evaluation of 9percent of the scale.",
