DAO

DAO is the acronym for Drug Abuse Ontology.

The PREDOSE research team at Knoesis has developed preliminary techniques that automatically extract semantic information from Web-based data. Such includes entities, generic sentiment expressions,  relationships and triples. To perform entity identification, the research team relies on a combination of lexical and semantics-based techniques, based on a manually curated Drug Abuse Ontology (DAO) - pronounced dow), which is the first ontology for prescription drug abuse.
