Maintenance of an occupations and skills taxonomy like ESCO is a challenging and labourintensive process. This process needs to ensure high quality content in the context of a constantly changing labour market.

While there exist numerous indicators reflecting the quality of the classification, among the most significant ones are those related to consistency. Two indicators in particular are the consistent allocation of occupations and skills with respect to the existing underlying hierarchy and the accuracy of relations across occupations and skills. In a series of news articles, we will focus on the occupations pillar of ESCO and outline how artificial intelligence (AI) assists in the process of maintaining ESCO.
