Typology of Drug Misuse Created from Information Available in Health Fora.

Patients seldom report the misuse of drugs to their physicians. Hence, other sources of information are necessary for studying these issues. We assume that online health fora can provide such information and propose to exploit them for building a typology of drug misuses. The misuses detected are structured according to the goals of patients: we distinguished three types of non-intentional misuses and 14 types of intentional misuses. This work will be used to guide future task of automatic extraction of drug misuses.
