Contextual property detection in Dutch diagnosis descriptions for uncertainty, laterality and temporality ...

However, healthcare providers frequently modify coded diagnoses by including or removing common contextual properties in free-text diagnosis descriptions: uncertainty (suspected glaucoma), laterality (left glaucoma) and temporality (glaucoma 2002).
