A content-based matrix factorization model for recipe recommendation

Abstract

This paper aims at bringing recommendation to the culinary domain in recipe recommendation. Recipe recommendation possesses certain unique characteristics unlike conventional item recommendation, as a recipe provides detailed heterogeneous information about ingredients and cooking procedure. Thus, we propose to treat recipes as an aggregation of features, which are extracted from ingredients, categories, preparation directions, and nutrition facts. We then propose a content-driven matrix factorization approach to model the latent dimension of recipes, users, and features. We also propose novel bias terms to incorporate time-dependent features.
