• Measuring the quality – a quality assessment - in general- provides insight into the quality and usability of web-scraped data for producing official statistics. The quality assessment in this presentation is about Online Job Advertisements (OJA). The OJA data was assessed in a couple of ways by members of the WIN project. Firstly, the quality and stability of the sources were assessed with the help of quality indicators that were formulated for this task. Secondly, the accuracy of the classification of the OJA data was assessed through annotation exercises. We They present the quality indicators and how they are operationalised in a reproducible manner for several countries.
