Drug Abuse Ontology

Drug Abuse Ontology (DAO) PREDOSE uses web forum posts and domain knowledge, modeled in a manually created Drug Abuse Ontology (DAO – pronounced dow), to facilitate the extraction of semantic information from User Generated Content (UGC), through the combination of lexical, pattern-based and semantics-based techniques. In a previous study, PREDOSE was used to obtain the datasets from which new knowledge in drug abuse research was derived. Here, we report on various platform enhancements, including an updated DAO, new components for the relationship and triple extraction, and tools for content analysis, trend detection and emerging patterns exploration, which enhance the capabilities of the PREDOSE platform. Given these enhancements, PREDOSE is now more equipped to impact drug abuse research by alleviating traditional labor-intensive content analysis tasks.
