AddictO Vocab
AddictO Vocabulary is an ontology of more explicit terminology in addiction and for e-cigarette research. It's effectively a dictionary expressed in RDF/OWL format, a documentation scheme suitable for semantic web applications, search engines, and machine reasoning. Notably it started as "EcigO" terminology, but is now merged into a broader set of terms about addiction in general. It's developed and curated by Robert West, Sharon Cox, Caitlin Notley, Kirstie Soar, Janna Hastings, with funding from Cancer Research UK.

The frontend website allows for browsing, but for more detailed introspection on the RDF document, Protege could be used (open source and cross-platform).
