Example smoking annotations in electronic medical records. The boxes around selected words highlight those the HITEx system picked up as informative regarding smoking status. The second column provides the system's classification of the smoking status. This illustrates the challenges for which additional tuning was required. For example, the “tobac” in Lactobacillus is no less obvious to HITEx, initially, than the “tob” in “tob/alcohol.”
