The Addiction Ontology (AddictO) is an ontology for representing entities relevant to all aspects of addiction research and clinical practice. It includes the E-Cigarette Ontology (E-CigO) which covers all substantive entities that may be referred to in research reports and commentaries relating to e-cigarettes.

The project is being developed using the BFO upper level ontology and following best practices as set out by the OBO Foundry.

It is funded by the Society for the Study of Addiction with the E-Cigarette Ontology supported by Cancer Research UK and is expected to underpin a new tool for semantically annotating research reports that are submitted to the journal Addiction, the Addiction Paper Authoring Tool.

The ontology content can be browsed at http://addictovocab.org, and a downloadable version of the ontology is available at http://addictovocab.org/addicto.owl.

Contributors to the Addiction Ontology (current and past) include: Robert West, Simon Christmas, Janna Hastings, Ildiko Tombor, Susan Michie, Sharon Cox, Caitlin Notley, Michael Lynskey, Paul Toner, Kirstie Soar.

The Addiction Ontology project relies on ontologies developed in the context of the Human Behaviour-Change Project such as the the Behaviour Change Intervention Ontology (BCIO). It furthermore harnesses content from the Mental Functioning (MF) and Emotion (EM) ontologies.
