Estimating tagging accuracy at the BBC

Presenter(s): Tatjana Mladenovic (BBC)

The application of descriptive content metadata to content (content tagging) is well established at the BBC. Tags can be applied manually by editorial teams, and they are increasingly made by automated metadata systems. But how do we measure and compare the quality of these taggings coming from different sources? This presentation demonstrates the work done on estimating tagging accuracy as part of a metadata quality project and how it has been implemented in BBC tagging systems.
