RECIPES DATASET DESCRIPTION the description refer to dataset/foods/CSV/foodDataset.xlsx Feature name Description Name italian name of the recipe ID ID associated to the recipe Link link of where the food data has been get Category Name name of the category (Starter, Complete Meal, First Course, Second Course, Savoury Cake) Category ID ID associated to the category Cost cost indicator of the food, discrete interval from 1 to 5 Difficulty difficuly indicator of the food, discrete interval from 1 to 4 Preparation Time integer positive number that indicates preparation time of the food expressed in minutes Ingredient english name of an ingredient of the recipe Ingredient ID ID associated to the ingredient Weight weight that the ingredient has in the composition of the interested recipe ... the columns of ingredients repeats for 18 times, leaving empty spaces when the recipe has no ingredients other than Preparation english name of a preparation performed on the recipe Preparation ID ID associated to the preparation Weight weight that the preparation has in the composition of the interested recipe ... the columns of preparations repeats for 18 times, leaving empty spaces when the recipe has no preparations other than in other sheet of the file are reportet all the ingredients, divided in classes and metaclasses, preparations and categories NOTE: in dataset/foods/TXT/textData.txt ingredients and preparation has been vectorized as follow: each element of the ingredient vector represent the weight of the ingredient class in the recipe. The weight of an ingredient class in a recipe is collected by sum up the weight of the ingredients owned by that particular ingredient class in the recipe. each element of the preparation vector represent the weight of the preparation in the recipe. PREFERENCES DATASET DESCRIPTION In the file dataset/survey_answer/samples.txt are reported 54 user's orderings in the form of pairwise comparison. Thus for each row correspond the ordering of a user. The ordering is written in the form of pairwise comparison, so each element of the ordering are paired with all others (avoiding simmetries). For instance, given the recipes as their ID: 1; 2; 3 becomes: 1,2; 1,3; 2,3 The file is written following the .csv format. In the file dataset/survey_answer/lables.txt are written the correspongin labels of the couples. The label has value 1 if the first element of the couple is preferred over the second, -1 if the second element is preferred over the first, 0 if there is uncertainity about which of the element is preferred.
