Modeling recipes for online search

In this paper we propose a formal model which allows us to effectively represent and search for recipes in online environments. The proposed model is an entity- relationship model that provides relevant entity types and properties, formalized as an ontology. The important aspects of the recipe model are identified by means of competency questions. Our model advances the state of the art in that it supports essential queries that are typically not supported by websites and current reference data models, such as Schema.org and the BBC Food Ontology. We illustrate the methodology followed, the developed model, and the evaluation we conducted.
