We built food ontology primarily to support comparative effectiveness researchers studying food components or ingredients data. Food Ontology Knowledgebase (FOKB) is developed in English and Turkish that contains details of food ingredients such as their codes (e-codex or codex numbers) and also side effects of them such as allergy. Initially, the first stage of the research project was funded in 2013 by TUBITAK (The Scientific and Technological Research Council of Turkey- http://www.tubitak.gov.tr/en) – 1512 Progressive Entrepreneurship Support Program (Project No: 2120357, “Semantic-based Personal Safe Food Consumption System for Allergic Individuals via Smart Devices”) by the Semantica Trd. Ltd. Co (http://www.semantica.com.tr/en). The initial proposal of the first stage project is presented in Hindawi Publishing Corporation http://www.hindawi.com- The Scientific World Journal with the title “FoodWiki: Ontology-driven Mobile Safe Food Consumption System”. After that, another project as an extension of the first stage project was funded again by TUBITAK toward the end of 2014. It is titled “Artificial Intelligence-based Mobile System for Conscious Food Consumption through Ontology” and recorded with the project number 3140417 in cooperation with Semantica Internet and Software Services Trd. Ltd. Co. and Acıbadem Hospitals Group in consultation with Asst. Prof. Dr. Duygu Çelik. Copyrights of the Food Ontology Knowledgebase (FOKB) and FoodWiki system are reserved by Semantica Trd. Ltd. Co and Acıbadem Hospitals Group (http://www.acibademinternational.com/).
