Illustration of the process to compute the product roles from the recipe data, where cyan squares are recipe nodes, orange circles are ingredient nodes, red circles are product nodes, the line thickness corresponds to how high the corresponding scores are, and \(l_{0}\) substitute roles, l complement role(s) and \(l_{1}\) substitute roles are shown as groups of product nodes in the purple dashed circles, green dashed polygon(s) and blue dashed circles, respectively
