The Corpus Of Patient Opinions in Dutch (COPOD) has been built by crawling the well-known medical forum Zorgkaart Nederland on June 28, 2016. It is composed of 156,975 patient reviews about their experiences with physicians of 60 specialties. Each review contains a rating for different aspects (accommodation, appointment, therapy, staff attention, information and listening), on a scale from 1 to 10 stars, and an overall rating that corresponds to the average of the ratings of these aspects.
