Data quality: a glimpse into our annotation team

As you hopefully know, at Dataprovider.com we index the entire internet on a monthly basis and structure the data. In order to meaningfully structure data we frequently need to classify data, detect new data and assess data quality. For example, in order to determine to which country a website belongs, you generally need to take various sources of information into account such as the language used on the website, whether there is an address or where the website is hosted.
