From: Mining Adverse Drug Reactions from online healthcare forums using Hidden Markov Model
Model of a forum message containing drug and side-effect information. A forum message containing mentions of drug and its associated side-effects is modeled using an Hidden Markov Model. The presented model represents an ergodic HMM where every state is connected to every other state including itself and allows for transitions between each of them. This models a forum post where the mentions of drug names, side-effects, keywords and other words can appear in any sequence with possibilities for repetition.
